Safety Precautions Please observe the following precautions to ensure the safety of service engineers as well as operators when using this system. &ANGER: D o no t use flammable gases such as anesthetics, or flammable liquids such I as ethanol, near this product, because there is danger of explosion. I ,&ARNING: 1. Information concerning the terminal to which the potential equalization conductor is to be connected ( ): To use another medical device in combination with this system, an equipotential wire for connecting to an equipotential bus must be supplied. For more information, contact your TOSHIBA representative. * Be sure to connect the potential-equalization lead wire before inserting the equipment power plug into the receptacle. Also, be sure to remove the equipment power plug from the receptacle before disconnecting the wire to avoid electrical shock. 2. Information concerning the functional earth terminal (6): Use of the functional earth terminal as protective earth is not allowed in Europe. The system should be connected according to local requirements. 3. Do not connect this system to outlets with the same circuit breakers and fuses that control current to devices such as life-support systems. If this system malfunctions and generates an overcurrent, or when there is an instantaneous current at power ON, the circuit breakers and fuses of the building’s supply circuit may be tripped. 4. Do not connect to the system transducers other than those specified by TOSHIBA, to prevent accidents such as fire. 5. Do not subject the transducers to knocks. Use of defective transducers may cause an electric shock. ACAUTION: 1. Malfunctions due to radio waves (1) Use of radio-wave-emitting devices in the proximity of this kind of medical electronic system may interfere with its operation. Do not bring or use devices which generate radio waves, such as cellular telephones, transceivers, and radio controlled toys, in the room where the system is installed. (2) If a user brings a device which generates radio waves near the system, they must be instructed to immediately turn OFF the device. This is necessary to ensure the proper operation of the system. s-2

[Page 6] A - CAUTION: 2. Be sure to install the system on a level floor and lock the casters. If this is not done, the system may move, injuring the service personnel. 3. Move the system forward or backward only. If the system is moved to the left or right, it may fall, causing injury. In addition, be sure to fix the moving sections such as the operating panel before moving the system. If such sections move, they may catch the hands or fingers of the persons moving the system, possibly causing injury. 4. To prevent electric shock, do not connect the peripheral units (video printer, VCR, etc.) to an external outlet. Peripheral units should be connected to the service outlet of the system or the optional isolation transformer. For the connection procedures, contact your TOSHIBA representative. 5. The service outlet of the main unit is intended solely for recommended peripheral units. Do not connect devices other than recommended peripheral units to the service outlet. Connecting devices other than those recommended may cause the consumption current to exceed the power capacity of the main unit, possibly resulting in malfunction. 6. Do not place any objects on top of the monitor. They may fall, causing injury. 7. Do not allow fluids such as water to contact the system or peripheral devices. Electric shock may result. 8. Do not handle the system with wet or moist hands. Electric shock may result. 9. The monitor is a heavy unit. Two persons are required when mounting or removing the monitor. If a worker mounts or removes the monitor alone, he/she may be injured. 10. Be sure to turn OFF the power breaker and disconnect the mains plug from the outlet before removing the covers of the main unit and performing internal wiring. 11. When discarding any part of this system, follow all applicable local regulations. 12. Wear protective gloves to ensure safety and prevent infection when performing unit replacement, board replacement, internal wiring, or cleaning. 13. Wait at least 30 seconds after turning OFF the power breaker and disconnecting the mains plug from the outlet before replacing the battery. Otherwise, an electric shock may result. CAUTION: I. When replacing the AC/DC tray of the SSA-770A, check the revision number of the AC/DC tray supplied for replacement and follow the appropriate procedure according to the revision number. 1 .I When the new AC/DC tray is BSM31-2013E (no revision) The AC/DC tray is not compatible and must not be used to replace the existing tray. s-3

[Page 7] CAUTION: 1.2 If AC/DC tray BSM31-2013E-G or BSM31-2013E-I is supplied (1) Wind the cables around the core as described below. (a) Wind the FAN/RELAY signal cables (two lines) between the AC/DC tray and transformer tray ONE time around the core (TWO turns). * When the cable is passed through the core the first time it is counted as one turn. Therefore, winding of the cable one time corresponds to TWO turns. (b) Wind the LED signal cable (which is connected to the top of the AC/DC tray) between the AC/DC tray and the transformer tray ONE time around the core (TWO turns). * When the cable is passed through the core the first time it is counted as one turn. Therefore, winding of the cable one time corresponds to TWO turns. (2) The metal sheet for EMC compliance should not be installed. 1) (b) Core for the LED signal cable (1) (a) Core for the FAN/RELAY Wind the cable ONE time around s-4

[Page 8] CAUTION: 1.3 When the new AC/DC tray is BSM31-2013E-H or -J or later (revision or later) (1) Wind the cables around the core as described below. Note the number of times each cable is to be wound around the core. (a) Wind the FAN/RELAY signal cables (two lines) between the AC/DC tray and transformer tray FOUR times around the core (FIVE turns). * When the cable is passed through the core the first time it is counted as one turn. Therefore, winding of the cable four times corresponds to five turns. (b) Wind the LED signal cable (which is connected to the top of the AC/DC tray) between the AC/DC tray and the transformer tray ONE time around the core (TWO turns). * When the cable is passed through the core the first time it is counted as one turn.

[Page 104] 4. OPERATION OF EACH PWB 4.1 Front-End Unit The front-end unit consists of the Transducer Interface board (TI), the three Transmit/Receive boards (TR), the Receive Control board (RC), and the Continuous Beamformer board (CB). (2) Composition Transducer Interface board (TI) The TI board includes the three array transducer connectors and the CW pencil transducer connector. This board enables switching between the transducers. Transmit/Receive boards (TR) Simultaneous transmission/reception for a maximum of 192 channels is performed on the three TR boards. In addition, the transmission delay control and reception gain control functions are provided. Receive Control board (RC) This board performs reception phasing/addition in quad signal processing (up to 192 channels). In addition, the Real Time Control circuit (RTC), which controls the front-end unit, is provided. Continuous Beamformer board (CB) This board performs reception phasing/addition control and quadrature detection for the SCW by inputting 64 channels. This board includes the signal processing circuit, ADC, and dedicated transmission/reception circuit for the Pencil CW. 4-l

[Page 105] (3) Flow of signals in the front-end unit (a) Transmission system Transmission data from the RTC in the RC board is transferred to the TXPG in the TR board. The transmission delay and transmission waveform data are set. The TXPG has a transmission reference clock (40 MHz, four-phase) and outputs the trigger signals HOUT/LOUT to the PULSER based on the clock. The PULSER outputs a bipolar transmission signal based on the trigger signal. The transmission signal is output to the transducer connector port that is selected in the transducer port selector of the TI board. (b) Reception system The reception echo signal flows in the direction opposite to the flow of the transmission drive signal via the same route and is input to the reception circuit in the TR board. The reception signal is input to the RXAR-ASIC (PREAMP-IC). The signal is amplified by the specified amount and is input to the RXBF-ASIC in the RC board. The input signals are AD-converted in the RXBF-ASIC and reception beam forming is performed. Beam forming is performed simultaneously in a maximum of four directions and the beams are output to the BE board. (c) SCW transmission/reception system The SCW transmission system is the same as that described in (a) above. The 64-ch reception signal output from the TR board is input to the CB board that is connected to the RC board in parallel. In the CB board, quadrature detection is performed in the demodulator after reception analog beam forming. Then baseband signal processing is performed and the signals are AD-converted. The I/Q signals that have undergone AD conversion are converted to serial data and are then output to the BE board. (d) Pencil CW transmission/reception system The CB board includes the pencil CW transmission/reception circuit. The transmission output signals in the CB board are passed through the pencil transducer connector connected to the TI board using the cable and are then output to the pencil transducer transmission elements. The echo signals received in the pencil transducer are also passed through the TI and are input to the reception system in the CB board. After the signals are amplified in the pencil CW receiver circuit in the CB board, they are passed through the demodulator or later blocks and are AD-converted. 4-2

[Page 108] 4.1.1 TI The TI board (Transducer Interface board) includes the three array transducer connectors and enables switching of the transducers to be connected to the pulser/preamplifier. (2) Description of functions and operation (a) Array transducer switching This board contains the three 360-pin ZIF connectors for the array transducers and switches between the 192-ch echo line and the required control line using a relay. The transmission/reception signals are transferred to the pulser/preamplifier mounted on the TR board through the Backplane board. (b) Pencil transducer transmission/reception signal connection The connector box for the pencil transducer is installed in the cabinet and is thus connected to the TI board via a cable. The transmission/reception signals coming from the pencil transducer are transferred to the pencil pulser/pencil preamplifier mounted on the CB board through the TI and Backplane boards. (c) Support of the M-TEE transducer l Thermistor line Transfers signals coming from the temperature detection thermistor embedded in the M-TEE transducer to the ADC mounted on the RC board. (Up to two thermistors are supported.) l Angle detection line Transfers signals coming from the angle detection potentiometer embedded in the M-TEE transducer to the ADC mounted on the RC board. (d) Support of transducer with impedance converter This board supplies power for collector bias of the impedance converter. An over- current detection circuit is provided. The emitter bias power supply is provided from the TR board. (e) Support of 1.5 D transducer including a HVSW l This board receives the control data for the HVSW embedded in the transducer (walking bus) from the RC board and transfers it to the transducer. l This board supplies f 100 V for the HVSW embedded in the transducer. (f) Power supply for circuit inside the transducer This board supplies + 5 V for the circuit inside the transducer. An over-current detection circuit is provided. 4-5

[Page 109] (g) Error detection The TI board includes detection circuits for the following errors a. HV fault error This error occurs if the voltage for the HVSW embedded in the transducer is not correct. b. HV detection fault error This error occurs under the following conditions. If this error occurs, the crowbar circuit operates and stops supplying f 100 V. l The f 100-V power for the HVSW embedded in the transducer is applied to a connector where no transducer is connected. l The f 100-V power for the HVSW embedded in the transducer is applied to a connector where a transducer that does not require a high voltage is connected. c. HV diode fault error The diode is set on the echo channel in order to clamp the echo channel to prevent application of the f 100 V. This error occurs if the diode is broken and a current resulting from the high voltage flows in the echo channel. d. Relay fault error This error occurs if a relay for switching the transducer has values that are different from those of the relay control register. e. Over-current fault error This error occurs if an over-current occurs in the power (+ 5 V for Zconv) supplied to the transducer. (h) Transmission disable signal generation The TI board transfers the transmission disable signal (TXDIS) to the TR boards under the following conditions. l An HV fault error is detected (a in (g)) l An HV detection fault error is detected (b in (g)) l An HV diode fault error is detected (c in (g)) l A relay fault error is detected (d in (g)) l An over-current fault error is detected (e in (g)) l The HVSW in the 1.5 D transducer is in transition l The transducer selection relay is in transition l The transducer ID of the selected transducer is changed l An empty transducer connector is selected 4-6

[Page 112] 4.1.2 TR The two primary functions of this board are first, to generate and deliver the transmit signals to the TI board, and second, to receive, amplify, and deliver the echo signals to the RC board. (2) Description of functions and operation (a) Transmit pulser This is the circuit which drives the piezoelectric elements inside the transducer electrically. The number of transmission waves and the pulse duration are controlled by the TXPG. The transmission pulse (bipolar transmission waveform) is generated in the circuit by increasing the low-voltage power supply in the transformer. In addition, this pulser has the two blocks in the transformer primary-winding side. Transmission voltage switching for each rate is achieved by applying different voltages to each of the blocks (dual pulser). (b) Transmit pulse generation The transmit pulse generation section is comprised of the following subsections: transmit control bus (TC bus), /TXCL and /TCWR signals, digital control, PECL clocks (four blocks), PECL synchronize signals (two blocks), power supply, 64 pairs of transmit control signals (Hout and Lout), and a transmit pulse generation ASIC (TXPG). (c) Preamplifier and variable gain amplifier (functions in RXAR ASIC) They amplify the echo signals from the piezoelectric element. The gain in the preamplifier is fixed to +I4 dB. The variable gain amplifier sets the gain from 0 to +75 dB by changing the control voltage (VTGC) from 0 to 1 V. (d) Antialiasing filter (functions in RXAR ASIC) This filter prevents the aliasing that occurs when the analog echo signals are converted to digital signals in the RC board. The cutoff frequency can be changed from 4 to 16 MHz by changing the control voltage (VAAC) from 0 to 1 V. The RXAR ASIC is set as given below in the SCW mode. The gain is fixed to 20 dB and the antialiasing filter is bypassed. 4-9

[Page 113] (e) T/R switch The T/R switch is used to switch the impedance of the echo signal channel between the transmit event and the receive event. During the receive event, this switch short-circuits the secondary transformer to provide a low echo signal channel impedance. (f) Address decoder (EPLD) and TC bus The address decoder uses digital control lines to perform the required control for the TR board. The address decoder serves as the “brains” of the TR board and communicates with the RC board via the TC bus. The TC bus serves as a bidirectional interface with the RC board. This bus is the digital communication hub for the TR board, which is used to access the memory in the TR address decoder, ID EEPROM, and TXPGs. The TC bus is comprised of two data buses and one address bus. The data bits are broken down into two 16-bit buses, TCOD[15:0] and TCI D[15:0], where each data bus is then connected to two TXPGs. TCOD[15:0] is sent to TXPG ASIC 0, TXPG ASIC 2, and the ID EEPROM, while TCI D[15:0] is sent to TXPG ASIC 1 and TXPG ASIC 3. (g) Reception resonance Reception resonance has been achieved by inputting inductance into echo signal lines in parallel. A coil is connected between the echo signal line and GND. There are four other inductance coils that can be selected. The resonance can be changed by using these inductance coils in various combinations. (h) Fault detection and protection circuit The TR board generates two types of interrupts: transmission interrupts and clock detection interrupts. a. Transmission interrupt A transmission interrupt is generated when TXENO and TXENI are both “H” simultaneously. This occurs only if there is a hardware fault or if the address decoder test bit is set. The address decoder EPLD always monitors the TXENO and TXENI lines and sets the interrupt status bit when it senses that both signals become “H” simultaneously. When this bit is set, the TR board stops transmission by making TXENO and TXEN 1 “L” and transfers the transmission inhibit signal and the interrupt signal to the system simultaneously to indicate that a system malfunction has occurred. This disables transmission to all three TR boards, not just the TR board where the error occurred. b. Clock detection interrupt A clock detection interrupt is generated when the PECL clock in the front-end unit stops before the TXPG completes transmission and the transmission for all three TR boards stops. This is extremely dangerous for the TR board because it leaves the TXPG output signals which drive the FET of the transmission circuit in an unknown state. If the TXPG output signals are fixed to “H”, the FET of the transmission circuit may be broken. 4-10

[Page 116] 4.1.3 RCB The RCB (Receive Control Board) controls the front-end section, AD-converts the reception signals, and performs receive beam forming. (2) Descriptions of functions and operations The RCB includes the following functions. (a) Front-end section scan control: RTC (Real Time Controller) block The transmission/reception in the front-end section is controlled according to control information from the RM. The RTC block consists of an FPGA (Field Programmable Gate Array, programmable IC) and SRAM. The sequencer set in the FPGA transmits data to each block of the front-end section according to the scan control information to be stored in the register in the FPGA and SRAM. (b) AD conversion and receive beam forming: RXBF (Receive Beam Former) block The reception signals obtained for every ch are AD-converted with a sampling frequency of 40 MHz and a quantification precision of 10 bits. The required reception delay is applied to each converted signal and addition is pet-formed. This block consists of 12 ASlCs (RXBF ASICs). (c) Analog control signal generation: Analog Control block The analog control signals required in the front-end section (listed below) are generated. They are obtained by performing DA conversion for the digital codes output from the RTC. l VTGC (time gain compensation) This signal controls the preamplifier gain depending on the depth of reception. This signal is input to the RXAR ASIC (preamplifier IC) in the TR board. l VAAC (antialias control) This signal is used to control the signal bandwidth before the AD conversion. This signal controls the cutoff frequency of the low-pass filter (antialias filter) in the RXAR ASIC. l TXV (transmit voltage control) This signal controls the transmission pulse voltage. The signal is input to the TR PWB via the power supply unit. l VMD (voltage for midpoint bias) This signal controls the bias point of the reception echo signal line between the TR board and RC board (between the RXAR ASIC and RXBF ASIC). The signal is input to the RXAR ASIC. 4-13

[Page 117] (cd) System clock generation: Clock Generation block The clock to be used in the system is generated. A 40-MHz clock is generated by dividing the 160-MHz crystal-oscillator frequency. (e) Self-diagnosis: Diagnostic Circuit block The line voltage and standard voltage in the front-end section are measured for self- diagnosis of the system. This block also includes the function for detecting the temperature of the TEE transducer head and angle of the piezoelectric element surface. The signals to be measured are selected by the multiplexer and are input to the AD converter. The converted data is transmitted to the RM via the RTC. A circuit which stops transmission forcibly when a certain regulation value is reached is provided for the transmission voltage and TEE transducer head temperature detection signals. (3) LED An LED (DSI) is set at the free edge on the RCB. If this LED lights, the FPGA of the RTC is configured (programmed). The FPGA is automatically configured when the power supply is input. Therefore, if the LED does not light even when the power supply is input, the RTC circuit is not configured and therefore the system does not operate. This problem may occur as a result of contact failure of the FPGA terminal, device failure, or damage to the ROM that stores the program. 0111 RTC (FPGA) k- (4) Error detection The RCB detects the errors described below. (a) Excessive transmission voltage detection The RCB monitors the transmission voltage output from the power supply unit to the TR board by the TXV as described before. If this control signal exceeds a certain set value, the RCB generates an error and stops transmission. The value is set by the register in the RTC. (b) TEE transducer head high-temperature detection The RCB is provided with a function that detects the temperature of the TEE transducer head. If the temperature exceeds 43”C, the RCB generates an error and stops transmission. In addition, since the RCB mainly controls the front-end unit, when an error occurs in the TI, TR, and CB boards, the RCB receives it temporarily. The RCB then outputs an interrupt request to the RM. 4-14

[Page 120] 4.1.4 CB (1) General description The CB board consists of the SCW channel adding circuit (summation), SCW/CW quadrature detection circuit, pencil CW transducer transmission/reception circuit, clock generation circuit, bus interface circuit, and self-diagnosis circuit. (2) Functions (a) SCW summation This function applies a delay of less than one period of the carrier waveform to the reception signals output from the preamplifier of the TR board and performs algebraic summation. (b) Quadrature demodulation circuit The band-pass filter (BPF) removes the higher harmonic elements. The mixer performs quadrature demodulation with the carrier frequency. The BPF and high-pass filter (HPF) located behind the mixer removes clutter elements. The selectable gain AMP circuit adjusts the levels of the Doppler signals, which differ depending on the type of transducer. The ADC converts the Doppler signals that have undergone quadrature demodulation to digital signals. These digital signals are then sent to the BE board. The phase and gain difference information in the sin/cos circuit is sent to IDPROM (5. Interface Section) and is corrected automatically in the BE board. If the correction is performed incorrectly, mirror artifacts increase. (c) Pencil CW TX/RX circuit The pencil CW TX/RX circuit is connected to the pencil transducer via the TI board. Bipolar transmission is used. For reception, Pencil CW mode is switched to SCW mode after the preamplifier. If switching is performed incorrectly, echoes from the pencil transducer cannot pass. (d) Clock generation circuit (pluse generator/LO) This circuit generates the clock which drives the pencil transmission circuit in the pencil CW TX/RX circuit, and also generates the reference clocks for the two mixers. These clocks are derived from the TXPG ASIC. If the TXPG ASIC is broken, images cannot be displayed in Pencil CW mode and SCW mode. (e) Inter-face The interface circuitry includes an address decoder EPLD, an ID EEPROM, a JTAG controller PLD, clock drivers, and buffers. 4-17

[Page 121] (3) Description of operation (a) SCW summation The SCW reception signals from the transducer are amplified to 20 dB (fixed gain of the preamplifier in the TR board) and are input to the 2nd preamplifier in the CB. The CB has a 64-ch reception signal line. When the sampling marker is moved in the SCW, the delay tap is selected accordingly from among the 16 taps on the delay line in the eight 8 x 16 multiplexers including 8 chs. Then algebratic summation is performed and reception beam forming is implemented. The delay time within one cycle of the carrier waveform is sufficient because the pulsed wave is periodic and a minimum quantification step of 20 ns is implemented with a maximum delay of 500 ns. The reception signals after algebratic summation differ depending on the type of transducer. Therefore the signal levels are matched using the variable attenuator RF gain and an appropriate dynamic range is allocated. The reception signals of the pencil (CW) and summation output of the SCW are switched by the multiplexer. Control of the 8 x 16 multiplexer, selection of the RF Gain, and output switching control between the pencil and SCW are performed by the address decoder (EPLD) based on the code of the TC bus from the RC. (b) Quadrature demodulation section 1) Selectable BPF The address decoder selects an appropriate band-pass filter (BPF) depending on the carrier frequency. 2) Quadrature demodulator A clock with a go-degree phase difference in carrier frequency is input to the two diode mixers and quadrature demodulation is performed for reception signals passed through the selectable BPF. The clock is generated by the TXPG based on the system clock (four-phase, 40 MHz) from the RC and is supplied to the mixer by shifting the level using the driver. 3) Baseband filter The DC (carrier elements) and added elements are eliminated by the BPF behind the mixer. The HPF behind the BPF is a fourth-order active filter and allows clutter elements to be removed. The required Doppler elements can be extracted The LPF is an antialiasing filter for the ADC and the cutoff is fixed to 156 kHz. This filter is a fourth-order active filter. 4-18

[Page 122] 4) Selectable gain amp The Doppler signal level differs for each transducer. Therefore, the signal level can be selected from 0 to 16 dB in 2-dB steps. Selection is performed by the address decoder (EPLD) based on code of the TC bus (BBGAIN). 5) ADC After performing IO-MHz sampling in Z-A type ADCs, the frequency element 156.25 kHz or more is eliminated in the digital filter and decimation is performed at the 312.5 kHz. The signals are output as serial data. The signals in the two ADCs (in-phase/quadrature-phase) are synchronized with the system clock via the EPLD and are output to the BE board. The I/Q signals in the two ADCs are combined into one synchronization signal with the serial data and they are then transferred in the differential format. (c) Clock generation circuit (plus generator/LO) In order to generate the reference clocks for mixers and the pencil CW transmission clock, the TXPG is configured to operate in infinite number of pulses mode (INPM). The PECL clock (four-phase, 40 MHz) is input to the TXPG and the frequency is set based on the TC bus data. (d) Pencil CW transmitter/receiver I> Pencil CW transmitter The pencil CW transmission circuit drives the pencil transducer piezoelectric elements. The TXPG outputs the clocks Houtl and Lout1 to the ACT08. This is controlled by the transmission enable signal (TXENI). The ACT08 drives the MOSFET and performs bipolar transmission by driving the transformer alternately. The transmission signal is transferred to the pencil transducer via the TI board. 2) Pencil CW receiver The reception signal returned from the pencil transducer is input to the preamplifier of the CB board via the TI board. After the weak signal from the transducer is amplified in the preamplifier, the CW receiver is connected to the selectable BPF and quadrature demodulation circuit by switching the multiplexer. The signal sent via the same route as for SCW summation and is processed. 4-19

[Page 123] (e) Inter-face 1) CB address decoder (EPLD) The CB address decoder (EPLD) decodes data from the TC bus and generates all the control signals required for the TXPG, ID EEPROM interfacing, control of buffer direction, and CB board. The TC bus is a bidirectional bus and consists of an 18-bit address, 16-bit data, an enable signal, and a handshaking signal. 2) PECL clocks The clocks for the CB board are derived from the PECL clock (four-phase, 40 MHz) RCFECK [0:3] output from the RC and the sync signal RCFECKE. The PECL clock is used in the TXPG. The clock converted from RCFECKO and RCFECK2 to TLL is used in the CB board. 3) ID EEPROM The ID EEPROM stores information related to the serial number, hardware revision, firmware revision, board ID, and drawing number. This device also stores the IQ calibration data that is used to correct the gain and phase differences between the in-phase and quadrature-phase circuits in the quadrature demodulator (quadrature demodulator circuit) on the BE board. The capacity is 8 k x 8 bits and this device is accessed via the CB address decoder EPLD and the TC bus. 4-20

[Page 138] 4.2.2 VI (Video Interface) The VI (Video Interface) board manages the system images from the BackEnd (BE) board, overlay graphics from the Realtime Manager (RM) board, and routes the system monitor video signal to the IO board. The VI also processes the NTSUPAL video signals in order to support external OEM devices. The VI manages the system audio and controls audio I/O to external devices. (2) Functions The functions implemented by the VI are outlined below: l Video processor display manager (ASIC) l Video processor image formatter (FPGA) l System video display mode control l Variable video resolution control l Bidirectional scaling engine for NTSUPAL l SVGA RGB encoding for system monitor l NTSC/PAL video decoding l NTSC/PAL video encoding l Simultaneous S-video, composite, and RGB analog output for NTSC/PAL l System audio control (I/O select, volume/tone control, LPF, HPF, etc.) l Doppler audio D/A conversion l System power supply control and status check l 64 bit, PCI bus interface l JTAG boundary scan interface 4-35

[Page 139] (3) Explanation of the block diagram The figure on the next page shows the top-level functional block diagram of the VI board. There are two separate PCI master/target devices on the VI board. One is the VPDM (video processor display manager) ASIC and the other is the VPIF (video processor image formatter) decoder FPGA. Each PCI master/target interface in the devices supports 64-bit address/data transactions at a 33-MHz bus speed. The PCI bus allows the VPDM to receive image data (e.g. 2D images, Doppler traces, ECG waveforms, etc.) from the BE board. It also allows both the VPDM ASIC and the decoder FPGA to communicate with each other. The digital SVGA link from the graphics subsystem of the RM to the VI carries 24-bit RGB data for the CPU overlay graphics and horizontal and vertical synchronization signals. The RM also sends the pixel clock signal to the VI, which is synchronized with the RGB data. The VPDM drives the system monitor through a triple 8-bit video DAC to display ultrasound images with superimposed overlay graphics. The maximum resolution supported will be 800x600 at a non-interlaced vertical refresh rate of 60 Hz for NTSC systems and 75 Hz for PAL systems. The 16-bit data bus from the VPDM to the VPIF encoder FPGA carries 16-bit YCbCr (4:2:2) non-interlaced video data with a resolution of 800x600 pixels. The VPDM sends video data that contains the video information displayed on the system monitor to the VPIF, where the data is converted to the NTSC/PAL image size and format and is then routed to the IO board. The NTSC/PAL video encoder receives image data in the 4:2:2 YCbCr format from the VPIF encoder FPGA and converts it to analog signals for an external monitor or a VCR The output analog signals are Y and C, color composite and RGB components. The NTSC/PAL video decoder converts analog Y/C signals from an external video device to image data in the 4:2:2 YCbCr format. Hsync, Vsync, field ID, and blanking information are included in the data stream. In VCR playback mode, the decoded VCR video data is scaled up and converted to non-interlaced video data in the VPIF decoder FPGA and is then sent to the VPDM via the PCI bus. The system audio control block provides input/output audio source select, volume and tone control, test tone generation, crossover networks, and audio D/A conversion. (4) Equivalent units in the PV series The functions of this PWB are equivalent to those performed by the RGB-CONV and TV- PROC in the PV series. 4-36

[Page 140] NTSUPAL encoder interface The “encoder” interface block refers to the external digital video encoder part used to generate NTSUPAL analog video signals. The 16 bit YCbCr data is converted into the CCIR-601 4:2:2 8-bit digital video format, including synchronization codes. This block also outputs disrete blanking, hsync, and vsync signal for diagnostics. The digital video output from the encoder FPGA includes additional blank lines and pixels in order to avoid problems with overscan in playback monitors. The NTSC timing is shown in the following table.

[Page 162] 6.6 PSAIPSD Unit The PSA/PSD unit is a DC/DC conversion-type multiple output power supply unit. This unit generates and supplies the DC power used to operate the system and the peripheral devices such as the system E/M (Electrical Module: electronic circuit board module), main panel, HDD, and FDD using the 48 VDC output from the AC/DC tray. The PSA/PSD unit consists of two modules: the analog power supply unit PSA (Power Supply Analog), which supplies power to the analog front-end circuitry, and the digital power supply unit PSD (Power Supply Digital), which supplies power to the digital back-end circuitry and the peripheral devices. (2) Specifications (a) PSA This is a multiple output power supply, including 12 fixed voltage outputs and 2 variable voltage outputs (14 outputs in total). The output power (with the suffix “AQ”) is supplied to the circuit handling echo signals in the system (such as the preamplifier) and therefore must have as low noise as possible. The variable output powers VTXO and VTXI (voltages for transmission) are used for transmission driving of transducers in the Aplio system and control the acoustic power emitted from the transducer directly. The Aplio system uses the dual pulser method and has two similar transmission drive pulsers. The two variable output powers VTXO and VTXI, which have the same output characteristics, are supplied to the drive pulsers. output output Supply direction output output Supply direction power name voltage circuit power name voltage circuit M2.0AQ -2.10 v Reception amplifier P14AQ -2.10 v Relay drive power etc. supply P3.3A +3.30 v F/E 3.3-V logic circuit M14AQ +3.30 v CB board -12-V etc. circuit etc. P3.3AQ +3.45 v Reception amplifier PI OOHV +100 v HVSW plus power etc. supply P5A +5.00 v F/E D/A circuit etc. MIOOHV -100 v HVSW minus power supply P5AQ +5.00 v Transmission EBN -3.00 v EchoBooster power predriver circuit etc. supply P7A +7.00 v CB board +5-V circuit VTXO +0.125 Pulser drive power to 18.0 V supply M9.6A -9.60 V CB board -5-V circuit VTXI +0.125 Pulser drive power to 18.0 V supply 6-7

Also, the ON/OFF control signal is supplied to the PSX from the AC tray and the PSX status signal I/F is supplied to the AC tray from the PSX. (3) Operational check (a) Precautions for operational checks Perform the operational check paying attention to the following points a. Do not touch the input 48-V line. An electric shock may result. (The PSA/PSD operates with 48 VI800 W.) b. Do not touch the output connectors during operation. An electric shock may result. (The PSA has outputs off 100 V.) c. Be careful when handling parts that may have a residual charge even after the power supply is turned OFF. An electric shock may result. (The residual charge in the output capacitors cannot be discharged immediately.) d. Do not disassemble units such as the PSX box by removing the cover etc. (The PSX is replaced as a unit.) 6-8

[Page 164] (b) Test point location Confirm the voltage at each output test point/GND test point using the tester. Be careful not allow the tester probe to cause a short circuit by creating a connection between the live line of the output and the metal cover, because the cover plate is connected to GND. (Even if the tester probe on the live line of the output comes into contact with the grounded metal cover, the output will not be short-circuited to the ground because an in- line hiah resistance of 4.7 k ohm is placed in series (with the live line of the output) insidethe PSX.)

[Page 184] 8. PHYSIO MODULE This module detects physiological signals (ECG, respiration, PCG, and pulse) using the ECG cable and sensors and transfers the data to the diagnostic ultrasound system (hereinafter referred to as “system”). Line voltage ECG (electrocardiogram) ICH (IM RESP (respiration) ICH) RESP (respiration) ICH DC IN (external inpuffECG) ICH (line voltage: f2.5 V) PCG (phonocardiogram) ICH Pulse (pulse) ICH AUX (external input) 1 CH (line voltage: f2.5 V) (2) Functions The following functions are provided. (4 Amplification of the electronic potential induced by the R and F electrodes of the ECG cable attached on the body surface and transfer of the data to the system in order to display the ECG on the monitor. Detection of the QRS waveforms and transfer of the signals to the system. Measurement of the electrical resistance in the chest with an alternating current (between electrodes R and F) and transfer of the data to the system in order to monitor the respiration cycle. (b) Transfer of respiration data from the thermistor sensor attached to the nasal cavity to the system in order to display the respiration cycle on the monitor. (cl Transfer of data from the PCG sensor attached to the chest to the system in order to display PCG waveforms on the monitor. (4 Transfer of data from the waveform sensor attached to the carotid artery and apex of the heart to the system in order to display pulse waveforms on the monitor. (e) Transfer of input signals (physiological signals) from two external medical devices to the system. The input signal from the one of the external medical devices can be output to the system as a trigger signal for imaging. (3) Operations This module consists of the amplifier section, power supply section, and digital section. The module is connected to the system via a cable and a 15pin D-sub connector. The module receives a 12-V power supply and waveform request command from the system and performs waveform (such as ECG and PCG) output to the system. The amplifier which amplifies the ECG, respiration, PCG, pulse, and external device signals is set inside this module. After importing the A/D values, the module calculates the sensitivity and position using the single-chip CPU inside the A/D converter and stores them in the RAM as digital values. QRS detection is performed by the hardware. The waveform data is output via a serial interface at a transmission rate of 312.5 Kbaud when a waveform request command is received from the system. QRS detection signals are output by setting QRS flags in the detection signals and waveform data (two series). Also, sensor connector insertion/removal information is transferred to the system. For the ECG connector, lead ON/OFF information, which indicates whether or not the three electrodes are attached to the patient properly, is output. 8-l

[Page 265] 17. 3D POSITION SENSOR 17.1 3D Position Sensor Unit The position sensor receiver of the 3D position sensor detects the magnetic field emitted by the position sensor transmitter. Based on this information from the magnetic field, the control unit of the 3D position sensor measures the three-dimensional position and direction of the position sensor receiver with respect to the transmitter, and transmits the results to the diagnostic ultrasound system (hereinafter referred to as “the system”). (2) Functions As shown in figure 17-1, the position sensor receiver detects the magnetic field in the three directions generated by the position sensor transmitter, and the control unit measures the three-dimensional position (x, y, z) of the position sensor receiver in the orthogonal 3D space around the position sensor transmitter. The control unit also measures the directions (a, 8, r) that represent the rotation angles of the coordinate system formed by the position sensor receiver as shown in figure 17-2. The control unit then transmits the obtained positional and directional data to the system. receiver Figure 17-1 Positional data Figure 17-2 Directional data 17-1

[Page 266] (3) Operations As shown in figure 17-3, the 3D position sensor consists of the control unit, the position sensor transmitter, the position sensor receiver, and the power unit. They are connected to the system by a cable and a g-pin D-sub connector. The power unit is supplied with 100/240 VAC by the system and supplies DC voltage to the control unit. The control unit receives the positional data transmission request command from the system and transmits a pair of positional and directional data sets (x, y, z: a, 8, y) via a serial interface (RS-232C) at IO-ms intervals. The data must be input to the COM2 port on the system, which is a serial interface*. The control unit calculates the position and directions based on the amount of current that is induced in the position sensor receiver in each of the three magnetic field directions x, y, and z that are generated at different times. * For a protocol, select a COM port not used by the VCR or 3D position sensor. The FLYKTDBY switch, which is intended to switch the status of the control unit between running and standby, must be set to FLY at all times. 1 AC1 00-240V Aplio Power unit COM2 I I D-Sub9 RS-232C POWER &OR b receiver Control unit rl Figure 17-3 System configuration 17-2

[Page 267] The intensity of the magnetic field generated by the position sensor transmitter becomes lower as the measurement point is moved away from the transmitter. The position sensor receiver must be within the spherical range from 21 cm to 76 cm from the center of the position sensor transmitter as shown in figure 17-4. In addition, the position sensor receiver must be within the front hemisphere of the magnetic field, which is one of the two hemispheres defined by the positive and negative directions on the x-axis, in order to assure the accuracy of the positional data. If the position sensor receiver is moved across the front and rear hemispheres during data acquisition, image reconstruction becomes impossible. ? :----- ---_ -. -. ‘\ ‘\ ‘\\ ‘1 Transmitter of the ‘, position sensor , 1 I _-: ir’ : I’ I’ If I’ /’ Back I’ , /’ /’ ,’ ,’ __dC .- i---- Figure 17-4 Position sensor transmitter The position sensor receiver is attached to a transducer using the dedicated attachment as shown in figure 17-5 (the transducer shown in the figure is the 375AT). Refer to the relevant operation manual for the procedure for attaching the position sensor receiver. Attachment Position sensor receiver Figure 17-5 Attaching the position sensor receiver to a transducer 17-3

[Page 268] The acquired 2D ultrasound image is accompanied with the size information on the 2D image itself and the positional and directional information of the position sensor receiver with respect to the position sensor transmitter. This information is used to reconstruct a 3D image. Therefore, it is necessary to correct the positional relationship between the position sensor receiver and the 2D-ultrasound image using a conversion table called a calibration matrix. The shape of the transducer is taken into consideration when the calibration matrix is prepared. Figure 17-6 Positional data 17-4

[Page 269] 17.2 Magnetic Field Distortion Check Tool The magnetic field distortion check tool is used to confirm that the magnetic field generated by the transmitter of the position sensor is not affected by the magnetic field environment in which the Aplio is installed. This check should be performed in the following cases. l By the service personnel during the installation of the Aplio system l By the user after the system installation environment is changed. l By the service personnel during maintenance work. l By the user as a part of daily checks. (2) Functions Since the operating principle of the 3D position sensor is based on the magnetic field as described in subsection 17.1, the magnetic field distortion in the area in which data acquisition is performed must be below the specified level. The magnetic field distortion check tool is designed to check whether the magnetic field distortion in the possible acquisition range is acceptable or unacceptable. (3) Procedure Place the position sensor receiver at each of positions A, B, and C that are located on a straight line at regular intervals. At each position, the receiver must be placed in the same orientation. Based on the positional and directional information at each check position, the magnetic field distortion check tool obtains the following three parameters: 1) direction at each position, 2) vector(p) between A and B, and 3) vector(q) between B and C. If the magnetic field is not distorted, these three parameters should be equal. Based on this rule, the check tool analyzes any errors in the actual magnetic field environment as compared with the ideal and determines whether or not the level of magnetic field distortion is acceptable.
