[Page 24] 1 - 8 HS50/HS60 Service Manual For information on User Key Setup, please refer to ‘Chapter 3. Utilities’ in the user manual. TIP Principles of Operation of the Diagnostic Ultrasound System Medical ultrasound images are created by digital memory and computer when they convert the high-frequency wave signals that are transmitted and received by the probe. As ultrasound waves propagate through the human body, they generate reflected signals whenever they encounter a change in density. For example, reflected signals are generated when signals pass from fatty tissues to muscle tissues. Reflected signals return to the probe, where they are converted into electronic signals. The reflected signals are amplified and processed by analog and digital circuits that have filters for various frequencies and response time options. Then they are again converted into high-frequency electronic signals, and saved as a series of digital image signals. The monitor displays the image signals stored on the storage device in real time. The entire process of transmitting, receiving, and processing signals is controlled by the computer.

[Page 25] Chapter 1. Introduction 1 - 9 1.2.2. Control Panel The system can be controlled by using the control panel.

Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, should be less than the compliance level in each frequency range ( ). Interference may occur in the vicinity of equipment marked with the following symbol: Note 1) At 80MHz and 800MHz, the higher frequency range applies. Note 2) These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects, and people. Field strengths from fixed transmitters, such as base stations for radio, (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcasts, and TV broadcasts cannot be predicted accurately. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location where the Ultrasound System is used exceeds the applicable RF compliance level above, the Ultrasound System should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the Ultrasound System or using a shielded location with higher RF shielding effectiveness and filter attenuation. Beyond the frequency range from 150kHz to 80MHz, field strengths should be less than 3 V/m.

[Page 56] 2 - 16 HS50/HS60 Service Manual A medical device can either generate or receive electromagnetic interference. The EMC standards describe tests for both emitted and received interference. Samsung Medison’s ultrasound systems do not generate electromagnetic interference in excess of the referenced standards. The Ultrasound System is designed to receive signals at radio frequency; therefore, it is susceptible to interference generated by RF energy sources. Examples of other sources of interference are medical devices, information technology products, and radio and television transmission towers. Tracing the source of radiated interference can be a difficult task. Customers should consider the following in an attempt to locate the source: • Is the interference intermittent or constant? • Does the interference show up with only one probe operating at the same frequency or with several probes? • Do two different probes operating at the same frequency have the same problem? • Is the interference present if the system is moved to a different location in the facility? The answers to these questions will help determine if the problem lies with the system or the scanning environment. Answer each of the questions and contact Samsung Medison's customer service department.

[Figure 2.3 Control Panel Caution]

[Page 60] 2 - 20 HS50/HS60 Service Manual 2.5. Biological Safety For safety information on the probe and biopsy, refer to ‘Chapter 9. Probes.’ • Ultrasound waves may have damaging effects on cells and consequently harm the patient. If there is no medical benefit, minimize the exposure time and maintain the ultrasound wave output at low levels. Refer to the ALARA principle. • Do not use the system if an error message appears on the video display indicating WARNING that a hazardous condition exists. Take note of the error code, turn off power to the system, and call Samsung Medison's customer service department. • Do not use a system that exhibits erratic or inconsistent functioning. Discontinuities in the scanning sequence are indicative of a hardware failure that should be corrected before use. • The system limits the maximum contact temperature to 43 degrees Celsius; the ultrasonic wave output observes the American FDA regulations. 2.5.1. ALARA Principle Guidance for the use of diagnostic ultrasound is defined by the '( A s L ow A s R easonably A chievable)' (ALARA) principle. The decision as to what is reasonable has been left to the judgment and insight of qualified personnel. No set of rules that would be sufficiently complete to dictate the correct response to every circumstance can be formulated. By keeping ultrasound exposure as low as possible while obtaining diagnostic images, users can minimize the ultrasonic bioeffects. Since the threshold for diagnostic ultrasound bioeffects is undetermined, it is the sonographer’s responsibility to control the total energy transmitted into the patient. The sonographer must reconcile the exposure time with the diagnostic image quality. To ensure diagnostic image quality and limit the exposure time, the Ultrasound System provides controls that can be manipulated during the exam to optimize the results. The ability of the user to abide by the ALARA principle is important. Advances in diagnostic ultrasound, not only in the technology but also in its applications, have given rise to the need for increased and improved information to guide the user. Based on a variety of ultrasound output data, the output indices are designed to provide important information for executing the ALARA principle. There are a number of variables that affect the way in which the output display indices can be used to implement the ALARA principle. These variables include mass, body size, location of the bone relative to the focal point, attenuation in the body, and ultrasound exposure time. Exposure time is an especially useful variable, because the user controls it. Unlike other variables, exposure time is entirely controlled by the operator of the ultrasound system.

[Page 61] Chapter 2. Safety 2 - 21 2.5.1.1. Applying ALARA The system-imaging mode used depends on the information needed. 2D-mode and M-mode imaging provide anatomical information, whereas Doppler, Power, and Color imaging provide information about blood flow. Scanned modes, like 2D-mode, Power, or Color, disperse or scatter the ultrasonic energy over an area, whereas an unscanned mode like M-mode or Doppler concentrates ultrasonic energy. Understanding the nature of the imaging mode being used allows the sonographer to apply the ALARA principle with informed judgment. The probe frequency, system setup values, scanning techniques, and operator experience aid the sonographer in adhering to the ALARA principle. The decision as to the amount of acoustic output is, in the final analysis, up to the system operator. This decision must be based on the following factors: type of patient, type of exam, patient history, ease or difficulty of obtaining diagnostically useful information, and potential localized heating of the patient due to probe surface temperatures. Prudent use of the system is secured when patient exposure is limited to the lowest index reading for the shortest amount of time necessary to achieve acceptable diagnostic results. Although a high index reading does not mean that a biological effect is actually occurring, it should be taken seriously. Every effort should be made to reduce the possible effects of a high index reading. Limiting the exposure time is an effective way of accomplishing this goal. There are several system controls that the operator can use to adjust the image quality and limit the acoustic intensity. These controls are related to the techniques that an operator might use to implement ALARA and can be divided into three categories: direct, indirect, and receiver control. 2.5.1.2. Direct Controls Application selection and output intensity control directly affect acoustic intensity. There are different ranges of allowable intensity or output depending on your selection. Selecting the correct range of acoustic intensity for the application is one of the priorities required during any exam. For example, peripheral vascular intensity levels are not recommended for fetal exams. Some systems automatically select the proper range for a particular procedure, whereas others require manual selection. Ultimately, the user bears the responsibility for proper clinical use. Samsung Medison's systems provide both automatic and user-definable settings. Output has direct impact on acoustic intensity. Once the application has been established, output control can be used to increase or decrease the output intensity. Output control lets you select intensity levels that are lower than the defined maximum. Prudent use ensures good image quality while employing the lowest output intensity.

[Page 62] 2 - 22 HS50/HS60 Service Manual 2.5.1.3. Indirect Controls Indirect controls are those with an indirect effect on acoustic intensity. These controls affect imaging mode, pulse repetition frequency, focus depth, pulse length, and probe selection. The choice of imaging mode determines the nature of the ultrasound beam. 2D-mode is scanned mode; Doppler is stationary or unscanned mode. A stationary ultrasound beam concentrates energy on a single location. Moving or scanned ultrasound beam disperses the energy over a wide area, with the beam concentrated only on a given area for a fraction of time necessary in unscanned mode. The pulse repetition frequency or rate refers to the number of ultrasound bursts of energy over a specific period of time. The higher the pulse repetition frequency, the more pulses of energy in a given period of time. Pulse repetition frequency is affected by several controls such as focal depth, display depth, sample volume depth, color sensitivity, number of focal zones, and sector width controls. The focus of the ultrasound beam affects the image resolution. Maintaining or increasing resolution at a different focus requires a variation of output over the focal zone. This variation of output is a function of system optimization. Different exams require different focal depths. Setting the focus to the proper depth improves the resolution of the structure of interest. Pulse length is the time during which ultrasonic burst is turned on. The longer the pulse, the greater the time-average intensity value. The greater the time-average intensity, the greater the likelihood of temperature increase and cavitations. Pulse length, burst length, or pulse duration is the output pulse duration in pulsed Doppler. Increasing the Doppler sample volume increases the pulse length. Probe selection affects intensity indirectly. Tissue attenuation changes with frequency. The higher the probe operating frequency, the greater the attenuation of the ultrasonic energy. Higher probe operating frequencies require higher output intensity to scan at an increased depth. To scan deeper at the same output intensity, lower probe frequency is required. Using more gain and output beyond a point without corresponding increases in image quality can mean that lower frequency probe is needed. ■ Receiver Controls Receiver controls are used by the operator to improve image quality. These controls have no effect on output. Receiver controls only affect how the ultrasound echo is received. These controls include gain, TGC, dynamic range, and image processing. The important thing to remember, relative to output, is that receiver controls should be optimized before increasing output. For example; before increasing output, optimize gain to improve image quality.

[Page 63] Chapter 2. Safety 2 - 23 2.5.1.4. Additional Considerations Ensure that scanning time is kept to a minimum, and that only medically required scanning is performed. Never compromise quality by rushing an exam. A poor exam will require follow-up, which ultimately increases the scanning time. Diagnostic ultrasound is an important tool in medicine and, like any tool, should be used efficiently and effectively. 2.5.1.5. Output Display Features The system output display consists of two basic indices: mechanical index and thermal index. The thermal index consists of the following indices: soft tissue (TIs), bone (TIb), and cranial bone (TIc). One of these three thermal indices will be displayed at all times. Which one is determined by the system preset or user choice, depending on the application at hand. The mechanical index is continuously displayed over the range of 0.0 to 1.9, in increments of 0.1. The thermal index consists of three indices, and only one of these is displayed at all times. Each diagnostic probe application has a default selection. The TIb or TIs is continuously displayed over the range of 0.0 to maximum output, based on the probe and application, in increments of 0.1. The default setting of the application-specific nature is also an important factor of index selection. A default setting is a system control state that is preset by the manufacturer or the operator. The system has default index settings for the probe application. The default settings are applied automatically by the ultrasound system when power is turned on, new patient data is entered into the system database, or change of application occurs. The decision as to which of the three thermal indices to display should be based on the following criteria: Appropriate index for the application: TIs is used for imaging soft tissue, and TIb, for focus at or near a bone. Elements such as fluid, bone, and blood flow may act as elements that increase or decrease TI. A highly attenuating tissue path, for example, may cause the potential for local zone heating to be lower than the thermal index displays. The selection of scanned modes or unscanned modes of operation also affects the thermal index. For scanned modes, heating tends to be near the surface; for unscanned modes, the potential for heating tends to be deeper in the focal zone. Always limit the ultrasound exposure time. Do not rush the exam. Make sure that the indices are kept to a minimum, and that exposure time is limited without compromising diagnostic sensitivity. ■ Mechanical Index (MI) Display Mechanical bioeffects are threshold phenomena that occur when a certain level of output is exceeded. The threshold level varies, however, with the type of tissue. The potential for mechanical biological effects varies with peak pressure and ultrasound frequency. MI accounts for these two factors. The higher the MI value, the greater the likelihood of mechanical bioeffects occurring. Note, however, that there is no specific MI value that means that a mechanical effect will actually occur. The MI should be used as a guide for implementing the ALARA principle.

[Page 64] 2 - 24 HS50/HS60 Service Manual ■ Thermal Index (TI) Display The TI informs the user of the potential for temperature increase occurring at the body surface, within body tissue, or at the point of focus of the ultrasound beam on bone. The TI is an estimate of the temperature increase in specific body tissues. The actual amount of any temperature rise is influenced by factors such as tissue type, vascularity, and mode of operation. The TI should be used as a guide for implementing the ALARA principle. The bone thermal index (TIb) informs the user of potential heating at or near the focus after the ultrasound beam has passed through soft tissue or fluid, such as the skeletal structure of a 2-3-month-old fetus. The cranial bone thermal index (TIc) informs the user about the potential heating of bone at or near the surface -- for example, the cranial bone. The soft tissue thermal index (TIs) informs the user about the potential for heating within soft homogeneous tissue. TIc is displayed when you select a trans-cranial application. Go to Setup > Imaging > Application/Preset > Thermal Index Type to select TI for display. ■ Precision and Accuracy of Mechanical and Thermal Indices Displays The Mechanical and Thermal Indices on the system are precise to 0.1 units. The MI and TI display accuracy estimates for the system are given in the Acoustic Output Tables section of this manual. These accuracy estimates are based on the variability range of probes and systems, inherent acoustic output modeling errors, and measurement variability as described below. The displayed values should be interpreted as relative information to help the system operator adhere to the ALARA principle through prudent use of the system. The values should not be interpreted as actual physical values of investigated tissue or organs. The initial data that is used to support the output display is derived from laboratory measurements based on the AIUM measurement standard. The measurements are then put into algorithms to calculate the displayed output values. Many of the assumptions used in the process of measurement and calculation are conservative in nature. Over-estimation of actual in situ exposure, for the vast majority of tissue paths, is built into the measurement and calculation process. For example, the acoustic output values measured underwater are de-rated using a conservative, industry- standard, attenuation coefficient of 0.3dB/cm-MHz. Conservative values for tissue characteristics were selected for use in the TI models. Conservative values for tissue or bone absorption rates, blood perfusion rates, blood heat capacity, and tissue thermal conductivity were selected. A steady-state temperature rise is assumed in the industry-standard TI models, and the ultrasound probe is assumed to be held steadily in one position long enough for a steady state to be reached. A number of factors that are considered when estimating the accuracy of display values include hardware variations, algorithm accuracy estimation, and measurement variability. Deviation among probes and systems in particular is an important factor. Probe deviation results from piezoelectric crystal efficiencies, process-related impedance differences, and sensitive lens focusing on parameter variations. Differences in system pulse voltage control and efficiencies are also a contributor to variability. There are inherent uncertainties in the algorithms used for estimating acoustic output values over the range of possible system operating conditions and pulse voltages. Inaccuracies in laboratory measurements are related to differences in hydrophone calibration and performance, positioning, alignment and digitization tolerances, and variability among test operators.

[Page 65] Chapter 2. Safety 2 - 25 The conservative assumptions of the output estimation algorithms of linear propagation, at all depths, through a 0.3dB/cm-MHz attenuated medium are not taken into account in the calculation of the accuracy estimate displayed. Neither linear propagation nor uniform attenuation at the 0.3dB/cm-MHz rate occurs in underwater measurements or in most tissue paths in the body. In the body, different tissues and organs have dissimilar attenuation characteristics. In water, there is almost no attenuation. In the body, particularly in underwater measurements, non-linear propagation and saturation losses occur as pulse voltages increase. The display accuracy estimates take into account the variability ranges of probes and systems, inherent acoustic output modeling errors, and measurement variability. Display accuracy estimates are measured according to AIUM measurement standards but not based on errors caused during measurement or inherent errors. They are also independent of the effects of non-linear loss on the measured values. 2.5.1.6. Control Effect- Controls Affecting the Indices Since various system controls are adjusted, the TI and MI values may change. This will be most apparent as the Power control is adjusted; note, however, that other system controls will also affect the on-screen output values. ■ Power Power controls the system’s acoustic output. Two real-time output values are on the screen: TI and MI. They change as the system responds to POWER adjustments. In combined modes, such as simultaneous Color, 2D-mode, and pulsed Doppler, the total TI is the sum of TIs of the individual modes. Each mode will be a dominant contributor to this total; the displayed MI will be from the mode with the largest peak pressure. 2.5.1.7. 2D Mode Controls ■ 2D Mode Size Narrowing the sector angle may increase the frame rate. This will increase the TI. The pulse voltage may be automatically lowered by the software controls to keep the TI below the system maximum. A decrease in pulse voltage will decrease the MI. ■ Zoom Increasing the zoom magnification may increase the frame rate. This will increase the TI. The number of focal zones may also increase automatically to improve the resolution. This action may change the MI, since the peak intensity can occur at a different depth. ■ Number of Focal Zones Increasing the number of focal zones may change both TI and MI by changing the frame rate or focal depth automatically. Lower frame rates decrease the TI. The displayed MI will correspond to the focal zone with the largest peak intensity.

[Page 66] 2 - 26 HS50/HS60 Service Manual ■ Focus Changing the focal depth will change the MI. Generally, higher MI values will occur when the focal depth is near the natural focus of the probe (transducer). 2.5.1.8. Color and Power Controls ■ Color Sensitivity Increasing the color sensitivity increases the TI and the time spent on scanning color images. Color pulses are the dominant pulse type in this mode. ■ Color Sector Width Narrower color sector width will increase the color frame rate; the TI will also increase. The system may automatically decrease the pulse voltage to below the system maximum. A decrease in pulse voltage will decrease the MI. If pulsed Doppler is also enabled, then pulsed Doppler will remain the primary mode, and the TI change will be small. ■ Color Sector Depth Deeper color sector depth may automatically decrease the color frame rate or change the color focal zone or color pulse length. The TI will change due to the combination of these effects. Generally, the TI will decrease with increased color sector depth. The MI will correspond to the peak intensity of the dominant pulse type, which is a color pulse. If pulsed Doppler is also enabled, however, then pulsed Doppler will remain the primary mode, and the TI change will be small. ■ Scale Using the SCALE control to increase the color velocity range may increase the TI. The system will automatically adjust the pulse voltage to below the system maximum. A decrease in pulse voltage will also decrease the MI. ■ 2D Mode Size A narrower 2D-mode sector width in Color imaging will increase the color frame rate. The TI will increase, but the MI will not change. If pulsed Doppler is also enabled, then pulsed Doppler will remain the primary mode, and the TI change will be small.

[Page 67] Chapter 2. Safety 2 - 27 2.5.1.9. M Mode and Doppler Controls ■ Simultaneous and Update Methods Use of combination modes affects both TI and MI through the combination of pulse types. During Simultaneous mode, the TI is an ancillary element. During Auto-update and Duplex, the TI will display the dominant pulse type. The displayed MI will be from the mode with the largest peak pressure. ■ Sample Volume Depth When Doppler sample volume depth is increased, the Doppler PRF may automatically decrease. A decrease in PRF will decrease the TI. The system may also decrease the pulse voltage to below the system maximum. A decrease in pulse voltage will decrease the MI. 2.5.1.10. Others ■ 2D, Color, M-Mode, PW, and CW Modes When a new imaging mode is selected, both TI and MI will change to default settings. Each mode has a corresponding pulse repetition frequency and a maximum intensity point. In combined or simultaneous modes, the TI is the sum of the contribution from the modes enabled, and the MI is the value for the focal zone of the mode with the largest de-rated intensity. If a mode is turned off and then reselected, the system will return to the previously selected settings. ■ Probes Each probe model available has unique specifications for contact area, beam shape, and center frequency. Settings are initialized when you select a probe. Samsung Medison's factory defaults vary according to the probe, application, and mode. Defaults have been chosen below the FDA limits for intended use. ■ Depth An increase in the 2D-mode depth will automatically decrease the 2D-mode frame rate. This would decrease the TI. The system may also automatically choose a deeper 2D-mode focal depth. A change of focal depth may change the MI. The displayed MI is that of the zone with the largest peak intensity. ■ Application Acoustic output defaults are set when you select an application. Samsung Medison's factory defaults vary with probe, application, and mode. Defaults have been chosen below the FDA limits for intended use.

[Page 69] Chapter 2. Safety 2 - 29 2.5.1.12. Acoustic Output and Measurement Since the first use of diagnostic ultrasound, the possible human biological effects (bioeffects) of ultrasound exposure have been studied by various scientific and medical institutions. In October 1987, the American Institute of Ultrasound in Medicine (AIUM) ratified a report prepared by its Bioeffects Committee (Bioeffect Considerations for the Safety of Diagnostic Ultrasound, J. Ultrasound Med., Sept. 1988: Vol.7, No. 9 Supplement), sometimes referred to as the Stowe Report, which reviewed available data on the possible effects of ultrasound exposure. Another report, “Bioeffects and Safety of Diagnostic Ultrasound” dated January 28, 1993, provides more up-to-date information. In addition, periodically updated reports on biological effects, results, and guidelines on safe use have been published by groups such as WFUMB (World Federation of Ultrasound in Medicine and Biology), AIUM, and BMUS. The Acoustic output for this system has been measured and calculated in accordance with the Standard for Real-Time Display of Thermal and Mechanical Acoustic Output Indices on Diagnostic Ultrasound Equipment (AIUM / NEMA, 2004) and the Acoustic Output Measurement Standard for Diagnostic Ultrasound Equipment (AIUM / NEMA, 2004) 2.5.1.13. In Situ , De-rated, and Water Value Intensities All intensity parameters are measured in water. Since water does not absorb acoustic energy, these water measurements represent the largest possible value. Biological tissue absorbs acoustic energy. The true value of intensity at any point depends on the amount and type of tissue and the frequency of the ultrasound that passes through the tissue. The intensity value in the tissue In Situ has been estimated using the following formula: − ( 0 . 23 alf ) In Situ = Water [ ] where: In Situ = In Situ Intensity Value Water = Water Value Intensity e = 2.7183 a = Attenuation Factor Tissue a(dB/cm-MHz) Brain .53 Heart .66 Kidney .79 Liver .43 Muscle .55 l = skin line to measurement depth (cm) f = Center frequency of the transducer/system/mode combination (MHz) Since the ultrasonic path during an examination is likely to pass through varying lengths and types of tissue, it is difficult to estimate the true in situ intensity. A 0.3 de-rating factor is used for general reporting purposes. Therefore, the in situ value is commonly reported using the following formula: − ( 0 . 069 lf ) In Situ (derated) = Water [ ]

[Page 70] 2 - 30 HS50/HS60 Service Manual Since this value is not the true in situ intensity, the term “de-rated” is used. The maximum de- rated and maximum water values do not always occur under the same operating conditions. Therefore, the reported maximum water and de-rated values may not be related to the In Situ (de-rated) formula. For example, a multi-zone array transducer has the greatest water value intensities in its deepest zone. The same transducer may have its largest de-rated intensity in one of its shallowest focal zones. 2.5.1.14.

[Page 128] Chapter 5. Product Structure 5 - 7 5.3. Basic Structure of the Product This product consists of the Ultrasound System Part and the User Interface Part. In the aspect of electronic structure, it consists of a Front End Part, a Back End Part, a User Interface Part, and a Power Part. The electronic structure of HS50/HS60 can be explained as follows: 5.3.1. Electronic Structure • Front End Part It consists of the PSA (Probe Select Assembly) and the BF (Beamformer). The Front End Part delivers High-Voltage Pulser to the probe to generate ultrasonic waves and amplifies the returning echo signal to process Digital Beamforming. The RF signal generated here is sent to the Back End Part. • Back End Part It consists of the BE (Back End) of the Ultrasound System Part as well as the PC Module. Raw data required to make diagnostic images (e.g., BW, Color Doppler, PW Doppler, and CW Doppler) from the RF signal generated by the BF (Beamformer) go through image processing in the form of DMA Packet by BE (Back End) and get transferred to the PC Module. Then, the data are displayed on screen via several steps of post-processing at the PC Module. New technologies such as MultiVision and ClearVision are adopted to show the image more clearly. • User Interface Part It consists of LED monitor, control panel, and touch screen. • Power Part It takes AC voltage and supplies AC power to the ADM and AUX Output via the circuit breaker. The ADM converts AC power into DC power, so it can supply voltage to the boards of the Ultrasound System as well as the PC module. 5.3.2. Ultrasound System Part It processes ultrasound data up to the stage before SW Post-Image Processing. This detects probes and performs TX Focusing and RX Focusing based on system and application information from the host in accordance with the user environment. When high-voltage Pulser is sent to the probe according to TX Focusing, ultrasonic waves are generated. Echo signals returning from the body due to the ultrasonic waves go through amplification and ADC to process Digital Beamforming. The RF signal obtained here goes through various filtering and processing to generate I/Q signals such as BW, Color Doppler, PW Doppler, CW Doppler, and Power Doppler, which are sent to the PC Part to generate image signals via SW Post-Image Processing. The AC to DC Power Module supplies power to the Ultrasound System Part. The Ultrasound System Part consists of the following: • PSA(Probe Select Assembly) Board • BF(Beamformer) Board • BE(Back End) Board • ADM (AC to DC Power Module)

[Page 129] 5 - 8 HS50/HS60 Service Manual 5.3.3. PC Part This displays the ultrasound information generated by the Ultrasound System Part. It consists of the Scan Converter and image output circuits.

The relay is operated by the probe select signal transmitted from the control logic (CPLD) of the CW (Continuous Wave Board). Probe Select signals are connected via the Back Plan Connector. ■ CW Pencil Probe Connection The Static CW Probe uses the coax-pin LEMO Connector. The LEMO Connector is located on a separate Connector Board and is connected to the PSA via cable. This connector consists of 2 coax-pins and 6 pins. 2 coax-pins are used for the TX/RX of Static CW, and 6 pins are used for the personality of Static Probe.

[Page 132] Chapter 5. Product Structure 5 - 11 5.4.2. Beam Former Board The Beamformer board is located between the PSA and Back End; it sends an ultrasound signal focused on a specific position of the body and amplifies the received signal to convert it into a Digital signal. Then, it beamforms the signal and relays the Focused data to the Back End for Mid-processing. The BF Board consists of Pulser, TR Switch, AFE, TX FPGA, ADC, and BF FPGA. [Figure 5.5 BF Board Image ] • Pulser: It consists of one 128-channel board and operates 192 element probes. The Pulser amplifies the entered firing signal into High-Voltage Pulse. • TR Switch: It adjusts the High Voltage from probes so that it cannot flow to the AFE • AFE: This amplifies the entered echo signal to a sufficient level, and then compensates the signal to a certain level. Finally, it converts the compensated signal into digital signal for RX Focusing. • BF FPGA: The BF FPGA covers 64 TX Channels per unit and outputs the TX Wave Data focused on TX. Moreover, it performs RX Focusing for 64 channels of RX echo signal per unit. Finally, it sums 128 channels of RX Focusing Data and sends them to the BE Part.

[Page 135] 5 - 14 HS50/HS60 Service Manual 5.4.2.2. Description ■ Transmit Channel Transmit Channel performs a function of applying high-voltage signal to the probe element, thereby generating ultrasound waves. It generates high-voltage pulse to transmit arbitrary waveforms from the BF FPGA. The Transmit Part consists of the BF FPGA and Pulser. ① BF FPGA The BF FPGA uses RTC signal to calculate the delay time for TX focusing and outputs a firing pulse to each TX channel. ② Pulser The Pulser amplifies the entered Firing Pulse signal into a high-voltage signal that is outputted to each element of probes. As a result, the probes vibrate to generate ultrasound waves. ■ Receive Channel Receive Channel amplifies the echo reflected from the medium in the human body. This signal is converted from analog into digital for beamforming at the BF FPGA. The BF FPGA sums the focused signal of each channel and sends the signals to the BE Board. The Receive Part consists of TR Switch, AFE, and BF FPGA. ① TR Switch Each element of the probes is connected in parallel to the TX Channel and RX Channel. Up to 180 Vpp Tx Pulse and mV-range Echo signals are mixed with each other. The RX data actually required is the echo signal in the mV range, which is a very weak signal. The TR Switch prohibits the high-voltage Tx Pulse from flowing into AFE input and permits low-level echo signals to pass. ② AFE HS50/HS60 uses the all-in-one type of AFE. One AFE performs the roles of LNA, TGC, and ADC for existing equipment. The AFE amplifies the mV-range echo signal input and performs gain compensation over time. It also transmits digitized RX Data to the BF FPGA. ③ BFX FPGA The BF FPGA performs RX focusing for each RX Channel data received from the AFE and sums the whole channel data. It then transmits the summed data to the BE Board.

[Page 136] Chapter 5. Product Structure 5 - 15 5.4.3. Back End Board The Back End Board (Below BE Board) includes three key features as follows: • RTC (Real Time Controller) / Host Interface • DMA (Direct Memory Access) Control • IQ Digital Signal Processing The RTC generates the control signals of the system and goes through the RF data entered in the BF board, and then transfers the DMA through the path. Digital Signal Processing implements some functions of the Mid Processor that is present in previous systems and transfers data to the SW DSC via DMA. Data reconfiguration for image implementation is handled by the FPGA, and image implementation is handled by the SW DSC . [Figure 5.9 Back End Board Top Side]

Digital Signal Processing (DSP) Part The Back End Board's MID FPGA (KINTEX325T) comprises the Digital Signal Processing Part, which transforms the Focused RF Data inputted by the BF Board into Base-Band IQ Data. The inputted RF Data goes through Gain Control, High-Pass Filtering, Quadrature Demodulation, and Decimation processes, and then gets sent to the DMA FPGA so that the Base-Band IQ Data can be transmitted to the PC SW Module.

[Page 139] 5 - 18 HS50/HS60 Service Manual 5.4.3.3. Host Interface & RTC Part ■ Host Interface The Host Interface integrated into the MID FPGA (KINTEX325T) is connected to the PC on PCI-Express 1Lane through PCI-Express Switch. The Host Interface converts the Host Command from the PC into Local Bus, so it provides an interface with each board of the Ultrasound System. ■ RTC Part The RTC (Real Time Controller), which is integrated into the MID FPGA, controls the operation of the system by generating the standard signals needed for the operation of the entire system in real time. It generates PRF (Pulse Repeat Frequency), OF (One Frame), RP (Rate Pulse), Linotype, and Scan Line, which are required for the BF Board and DSP Part of the BE Board. 5.4.3.4. DMA Part The Direct Memory Access (DMA) Part, which is integrated into the Back End Board's MID FPGA (KINTEX325T), consists of PCI-Express Gen1 1Lane to transfer large-capacity Base- Band IQ Data at high rate and performs the function of PCI-Express Interface within the FPGA. It has DDR3 SODIMM (4Gbyte) external memory in order to save large-capacity Base-Band IQ Data by frame.

[Page 195] 9 - 2 HS50/HS60 Service Manual 9.1. Probes The probe is a device that sends and receives ultrasound for acquiring image data. It is also called a Transducer or Scanhead. The system limits patient contact temperature to 43 degrees Celsius, and acoustic output values to their respective U.S. FDA limits. A power protection fuse circuit protects against over-current conditions. If the power monitor protection circuit senses an over-current condition, then the drive current to the probe is shut off immediately, preventing overheating of the probe surfaces and limiting acoustic output. 9.1.1. Probe List The ultrasound image scanner uses probes to obtain graphic data of the human body and then displays it on the screen. Always use application-specific probes in order to obtain the best quality images. It is also important to configure the probe with the best settings for the particular organ being scanned. ■ Probe Application and Presets The types of probes, applications, and presets available with this product are as follows: Small Parts Breast, Thyroid, Testicle LA3-14AD Vascular Carotid, Arterial, Venous, TCD GYN Uterus, Adnexa Linear Small Parts Breast, Thyroid, Testicle LA2-9A Vascular Carotid, Arterial, Venous, TCD GYN Uterus, Adnexa LA3-16AI Abdomen Abdomen, Renal, Bowel, Aorta

[Page 211] 9 - 18 HS50/HS60 Service Manual 9.1.2. Ultrasound Transmission Gel For proper transmission of the acoustic beam, only use ultrasound transmission gel approved by Samsung Medison. • The use of inappropriate ultrasound gels could result in damages in the probe. Using damaged probe could cause injuries such as electric shock in users or patients. • Do not use ultrasound gels or contact media that contain the following contents. – Oils such as mineral oil, cooking oil, gasoline, solvents, rust inhibitors, lanolin, paraffin-based grease, ester and excessive silicon-based release agent. – Alcohols such as acetone, methanol, plasticizer (dioctylphtalate) or denatured alcohols. – Glacial acetic acid and iodine. – All types of lotions or gels that contain aromatic substances. 9.1.2.1. Gel Warmer (Optional) The Gel Warmer keeps the ultrasound gel warm. Warming up ultrasound gel takes approximately 5 minutes. • Always turn the Gel Warmer off when it is not in use. • Do not put your hands inside the Gel Warmer, as it may burn your skin. • Do not use the Gel Warmer for purposes other than to control the temperature of ultrasound gel. • Do not place the probe or any other equipment inside the Gel Warmer. • Do not touch the power terminal of the Gel Warmer while you are examining a patient. There is a risk of electric shock from leakage current. • Do not apply excessive force to the Gel Warmer, or you may damage its support parts. [Figure 9.1 Gel Warmer Label – Example]

[Page 212] Chapter 9. Probes 9 - 19 9.1.3. Sheaths Sheaths are recommended for clinical applications of an invasive nature, including intraoperative, transrectal, transvaginal, and biopsy procedures. Using a sheath also prevents contamination from blood or other bodily fluids during operations or biopsy. Samsung Medison does not supply sheaths, so appropriate sheaths should be purchased independently. • Always keep sheaths in a sterile state. • Sheaths are disposable. Do not reuse them. • If sheaths are torn or soiled after use, clean and disinfect the probe. WARNING • In neurosurgical applications, a disinfected probe must be used with sterile gel and a sterile pyrogen-free sheath. • If the sterile sheath becomes compromised during neurosurgical applications involving a patient with Creutzfeldt-Jakob disease, the probe cannot be successfully sterilized by any disinfection method. • Some sheaths contain natural rubber latex and talc, which can cause allergic reactions in some individuals. Please refer to the FDA Medical Alert released on March 29, 1991. 9.1.3.1. Installing the Sheath 1. Remove the sheath from the packaging, and fill it with ultrasound gel. Be sure to put on sterilized surgical gloves. 2. Insert the probe into the sheath and pull the latex tip to cover the probe completely. If possible, cover the probe cable as well. 3. Ensure that there are no air bubbles trapped within the ultrasound gel. If necessary, secure the sheath to the probe and the probe cable. 4. Dispose of the sheath after use. 9.1.4. Probe Safety Precautions • Do not apply mechanical shock to the probe. • Do not place the probe cable on the floor where the cable can be run over by equipment wheels, etc. Do not apply excessive force to bend or pull the cable. • Do not immerse the probe into any inappropriate substances such as alcohol, bleach, ammonium chloride, and hydrogen peroxide. • Do not expose the probe to temperatures of +50 ° C or higher. The probe can easily be damaged by improper use or by coming into contact with certain chemical substances. Always follow the instructions in the user manual to inspect the probe cable, case and lens before and after each use. Check the probe for cracks, broken parts, leaks and sharp edges. If there is any damage, stop using the probe immediately and contact the Samsung Medison Customer Support Department. Using damaged probes may result in electric shocks and other hazards to the patients and/or users.

[Page 213] 9 - 20 HS50/HS60 Service Manual 9.1.4.1. Use and Infection Control of the Probe No neurosurgical treatments or examinations should be carried out on a patient with Creutzfeldt-Jakob disease. If the probe has been used on such a patient, it cannot be sterilized by any method whatsoever. Sufficient washing and disinfecting must be carried out to prevent infection. This is the responsibility of the user who manages and maintains the disinfection procedures for the equipment. Always use legally approved detergents. The ultrasonographic image scanner uses ultrasound, and makes direct contact with the patient when in use. Depending on the types of examinations, such contact can be made to a wide variety of locations, including the ordinary skin or the location of blood transfusion during a surgical procedure. The most effective method of preventing infection among patients is to use each probe only once. However, probes may need to be reused, as they are complex in design and expensive. Consequently, the safety instructions must be followed carefully in order to minimize the risk of infection among patients. 9.1.4.2. Electric Shocks The probe uses electrical energy. If it touches conductive materials, there are risks of electric shocks to the patient or the user. • The product should regularly be checked for electrical leakage by the Samsung Medison Customer Support Department. • Do not immerse the probe into liquid. • Do not drop the probe or apply mechanical shocks. • Inspect the housing, strain relief, lens, and seal for damage, and check for any functional problem before and after each use. • Do not apply excessive force to twist, pull or bend the probe cable. • The power protection fuse protects the probe and the product from excess current. If the power monitoring protection circuit detects excess current, it immediately shuts off the current to the probe in order to prevent the probe surface from overheating and to restrict the ultrasound power output. • The temperature of the product for making contact with patients is limited under 43°C. The ultrasound power output (AP&I) is in compliance with US FDA standards.

[Page 214] Chapter 9. Probes 9 - 21 9.1.5. Cleaning and Disinfecting the Probe Using an inappropriate cleaning or sterilizing agent may damage the probe. • Always use protective eyewear and gloves when cleaning and disinfecting probes. • Inspect the housing, strain relief, lens and seal for damage, and check for any functional problem after cleaning and disinfecting the probe. 9.1.5.1. Information of Detergent, Disinfectant, and Ultrasound Gel ■ Classification of Disinfectants To maintain the performance of ultrasound probes, proper maintenance is required. As ultrasound probes are classified into critical, semi-critical, or non-critical devices based on the standards of FDA guidance*, proper disinfection, cleaning or sterilization methods for that classification should be used. Classification Contact Area Application Probe Level Selection Criteria Non-critical Convex, Linear array, and Intact skin Low level disinfectant device sector transducers Semi-critical Mucous membrane and Endocavity High level disinfectant device damaged skin High level disinfectant or Critical device blood, sterile tissue, etc. Intraoperative, TEE sterilization *Guidance for Industry and FDA Staff - Information for Manufacturers Seeking Marketing Clearance of Diagnostic Ultrasound Systems and Transducers - Appendix D

Cleaning Cleaning is an important procedure that is carried out before disinfecting the probe. The probe must be cleaned after each use. • Do not use a surgical brush when cleaning probes. Even the use of soft brushes can damage the probe. • During cleaning and disinfection, keep the parts of the probe that must remain dry higher than the other parts during wetting until all parts are dry. 1. Disconnect the probe from the system. 2. Remove any biopsy adapters or needle guides. (Adapters may be reused after disinfection.) 3. Remove the sheath. (Sheaths are disposable.) 4. Use a soft cloth, lightly dampened with mild soap or compatible cleaning solution, to remove any particulate matter and bodily fluids that remain on the probe or cable. 5. To remove remaining particulates, rinse with water up to the immersion point. 6. Wipe with a dry cloth. 7. If necessary, wipe first with a water-dampened cloth to remove soap residue, and wipe with a dry cloth again.

[Page 229] 9 - 36 HS50/HS60 Service Manual 9.1.5.3. Disinfecting -6 A 10 reduction in pathogens should be reached following the disinfection procedures in this manual and using the following Samsung Medison recommended solutions. • If a pre-mixed solution is used, be sure to observe the solution expiration date. • The type of tissue it will contact during use dictates the level of disinfection required for a device. Ensure that the solution strength and duration of contact are appropriate for disinfection. • Using a non-recommended disinfectant or not following the recommended disinfection method can damage and/or discolor the probe. This could also void the probe warranty. • Do not immerse probes for longer than one hour, unless they are sterilizable. • Only use liquid solutions to sterilize probes. Do not sterilize by autoclaving or using EtO gas. 1. Please refer to the user instructions of the disinfectant for details of proper storage, use, and disposal of the disinfectant. 2. Mix the disinfectant compatible with your probe according to the instructions for solution strength provided on its label. 3. Immerse the probe into the disinfectant as shown in the illustration below. 4. Follow the instructions on the disinfectant to complete the immersion procedure of the probe, and rinse the probe afterwards. 5. Air dry the probe or towel it dry with a clean cloth. [Figure 9.2 Disinfection]

[Page 230] Chapter 9. Probes 9 - 37 9.2. Biopsy A biopsy is an examination method that surgically extracts tissue from the patient for examination. The probe and the biopsy kit are used together when conducting a biopsy with the ultrasonographic image scanner. The ultrasound system shows the needle, which penetrates through the skin surface and veins, along with the examination location, minimizing the risk to the patient. 9.2.1. Biopsy Kit Components The biopsy kit consists of the adapter, needle guide and needle. The components vary depending on the probe type. [Figure 9.3 Biopsy Kit Components] • Adapter: Secures the needle guide to the probe tightly. • Needle Guide: Guides the angle (direction) of the needle so that it can reach the examination location accurately. It also secures the needle so that the needle is not loose. • Needle: This is the needle that is inserted into the patient’s body. The biopsy kit supplied by Samsung Medison does not contain a needle. • Sheath: Prevents the probe and adapter from getting soiled by any unwanted substances during the examination (blood and other bodily fluids). • Ultrasound Gel: The space between the probe and the sheath is filled with the ultrasound gel to obtain images of the best quality.

[Page 231] 9 - 38 HS50/HS60 Service Manual 9.2.2. Using the Biopsy Kit • Only use the needles approved by the country’s government. • Verify the condition of the biopsy needle before use. Do not use a bent biopsy needle. • The biopsy needle may bend during tissue penetration. The precise location of the needle must be checked by monitoring the echo generated from the needle. • Never use the biopsy kit to biopsy prostate tissue. 9.2.2.1. Before Using Biopsy Kit • Do not attempt to use the biopsy kit until you have read the instructions for installing the sheath and verifying alignment of the needle guide. • Always ensure that the probe and the needle guide are secured on both the left and the right. • Do not use in IVF, CVS, or PUBS procedures. 1. Ultrasonographic scanning using the biopsy kit must be conducted by medical doctors or experienced medical staff with appropriate qualifications. Always, without fail, verify all safety procedures and disinfection. 2. Biopsy kits not supplied by Samsung Medison may fail to fit the probe properly. Always use biopsy kits supplied by Samsung Medison, since improper setup may adversely affect the patient. 3. Inspect all components. Ensure that the biopsy kit you are using is the correct one for the probe, the system, and system software. 9.2.2.2. Biopsy Procedure The system generates a needle guideline though the displayed real-time ultrasound images to indicate the anticipated path of the needle. You can use this guideline to ensure that the needle or instrument is following the correct path. 1. Ready the patient according to the procedure appropriate for the examination objectives. 2. Install the sheath and the biopsy kit. 3. Set the system controls for the biopsy procedure. If necessary, apply acoustic gel to the patient. 4. Scan the patient. Adjust the patient so that the location for examination fits into the needle guideline on the screen. 5. Insert the needle into the needle guide for use. Perform the puncture by sliding the needle through the groove in the guide until the needle intercepts the target. To keep the needle securely in the needle guide, press down on the top of the biopsy adapter with your index finger. 6. When the examination location is reached, take the needle out of the needle guide. 7. Detach the needle guide, adapter and sheath from the probe. 8. Discard all disposable items following use.

[Page 232] Chapter 9. Probes 9 - 39 9.2.2.3. Needle Guide Alignment • The needle used for this alignment verification must not be used for the actual procedure. Always use a new, sterile needle for each biopsy procedure. • To assist in accurate projection of the needle, use a straight, new needle for each alignment procedure. Alignment of the needle guide displayed on the system is for the purpose of verifying whether the needle and the needle guide are properly installed. This must be done prior to the biopsy examination. If the needle fails to follow the accurate path while verifying the alignment of needle guide, stop using the product and contact Samsung Medison Customer Support Department. Reverberation or other tissue artifacts may produce false needle images, which can cause confusion. Ensure the needle path is along the guideline, and that you are not using a false needle image to locate the needle. 1. Attach the biopsy kit. 2. Set the system depth for the procedure to be performed and select the Biopsy menu. 3. Immerse the probe into the water bath, and insert the needle into the needle guide. 4. Confirm that the needle image is on the needle guidelines. If it is, then the needle guide is properly aligned. 5. If the needle image is out of the needle guideline, check the needle guide or the probe adapter.
