gGeneral System Theory (continued)Scan Converter

The scan converter receive an analog ultrasound signal (with related information such as scan line number, depthand focus) from the scanner. The scan converter uses this signal to form the image.

Scan converter functions include:

• Digitize analog ultrasound information

• Store digitized ultrasound information for processing

• Post-processing

• Calculations

• Generate alpha-numeric and graphic overlays

• Interface front panel controls with recording devices

See scan converter function diagram and scan converter theory for additional information.

Power SuppliesThe main power supply (in the power supply drawer) converts 125 VAC to various regulated DC levels used in thesystem.

gGeneralThe scanner is located in the lower half of the system cabinet. Capacity is 67 circuit boards and the motherboard.

Transducers connect to the motherboard via the TDI board at the front of the system. Though there are twotransducer connection ports, only one can be active at a time. Communication between scanner and scanconverter is handled by the DBR board via a dual port RAM. Signal from the scanner to the Scan Converter passesthrough the DBL board.

Scanner operation is controlled by the SCP board. SCP is synchronized by the 10 MHz master clock located on theSTG Board.

Scanner sequence of operation is made up of three processes:

• Scanner Set-Up

• Transmission

• Reception

Scanner Set-UpThis sequence determines the type and number of lines to be fired by the transducer (based on control and gainsettings on the front panel) and passed to the scanner by the scan converter. Beamforming data is acquired fromthe DCC boards via the B, C, and D buses.

At the conclusion of this sequence, the transmission cycle begins.

TransmissionThe SCP board signal causes the XDY board to output the phased transmit pulse to the transmitter boards. The-high energy pulse required to drive the elements and produce an ultrasound wave on the probe face is then sent bythe XMT board.

Notes

gReceptionThe return echo signals from the transducer pass through the TDI board and scanner motherboard (SMB) to thereceiver (RCV) boards.

The receivers amplify and convert these low level signals to an intermediate frequency (IF), using the added signalsfrom the mixer clock (MXK) boards. Receiver board gain is controlled by a signal from the APD and IGD boards,which also compensate for signal loss (due to depth) and adjust the aperture of the array. The receivers output theIF signal to the SDL boards for summing.

Signals then pass to the DBL board to produce the IF SUM signal. The IF SUM signal is sent to thevideo detector (VDT) board where it is converted to an ultrasound video signal, amplified, and processed. Thesignal then returns to the DBL board for buffering. Finally, it is sent to the scan converter.

gOperating SequenceThe scan converter receives analog ultrasound beam data one line at a time from the scanner. Each line isdigitized, sampled, converted to pixel format and stored in the digital image memory. The data stored in the imagememory is read out, synchronized to the video display rate, converted to a composite video signal, mixed with theoverlay graphics, and delivered to the various output display devices.

gOperating Modes

2D Grayscale OperationThe scanner sends an ultrasound line (and line identifier) to the scan converter. The line goes to the Input Controller(IC) for initial processing, where it is digitized and sampled. Sampling rate depends upon operator settings, such asfield of view and magnification mode (RES). The data samples are sent through the IC for addressing, then to theCMB (under control of the Output Controller, OC) for storage in, and readout from, digital memory.

The CMB also handles grayscale processing (post-processing), temporal persistence, and buffer and storagefunctions. Buffering allows for synchronizing readout with the OC video raster scanning rate.

Digital data is read from CMB digital memory to the CVC. Here, digital data is converted to an analog signal,suitable for mixing with CVC overlay and graphics information. The combined data is synchronized to the videoraster rate and output to the CSI for distribution to viewing monitors, peripheral displays and recording devices.

Spectral Doppler OperationMost processing in this mode is done by the four boards dedicated to spectral and audio processing; DAQ, DSP,DCP and AUD.

The DAQ receives the Doppler line data and line identifier signals from the scanner. The line data is made up ofBBQ-generated I and Q quadrature analog ultrasound data. The control signals specify the line type as Doppler(instead of grayscale). The DAQ digitizes the I and Q signals and passes data to the DSP through the connectingribbon cables.

The DSP converts the Doppler signal from the time domain to the frequency domain. This allows for display thefrequency spectrum of the detected Doppler signal.

gSystem OverviewThe scanner power supply is inside the power supply drawer, between the wheels. Access can be gained from therear by removing the filters, cabling, and screws, then sliding it out on rails.

The power supply drawer contains four main sections. One section is a 300VDC coarse supply or HV bus. Thevoltage comes from the 340VAC step-up isolation transformer (T1) secondary winding. A bridge rectifier full waverectifies the voltage to 300VDC. It is filtered by a large inductor (L2) and capacitor (C3), and applied toPower Distribution Board 2 (PDB2).

This DC voltage powers the other three sections of the power supply drawer, each containing a switching regulator(DC-to-DC converter).

A fourth power supply is under the scan converter card cage. It is also a switching regulator, using the HV bus asa course supply.

The 340VAC isolation transformer also supplies 115VAC to all four switching power supplies, providinghousekeeping and control functions.

Synchronization for the four power supplies is provided by the clock signal (PERCLK), generated by theScan Control Processor (SCP) board in the scanner card cage. This signal is processed and distributed by PDB2.

PDB2 acts as the power supply control center. If an unusual demand is placed on any of the supplies, PDB2 shutsdown the system and displays an error code on the numeric LED. See Error Codes for more information.

Third 340VAC Rectified and supplied to:• Scanner Analog Supply• Scanner Digital Supply• Scan Converter Power Supply

These three supplies use 300VDC as both operating supply voltage and system supply voltage source.

A 0.5 A fuse protects the rectified and filtered 300VDC. It also protects a 150 Ohm bus load resistor, which protectsPDB2 from power surges at power-up. The resistor is on top of PDB2.

gPower-Up SequenceWhen the power switch is activated, PDB2 verifies:

• fans are active

• external AC is at least 95VAC

• temperature-sensing resistor is below 69°CIf these conditions are met, the Soft Start circuitry is energized.

AC is applied to the Isolation Transformer. AC input is conditioned by an electromagnetic inductance filter and a47 kOhm bleeder resistor (bleeds filter capacitor charge when system is unplugged from AC outlet).

A 12.5 Amp circuit breaker provides overcurrent protection.

PDB2 initializes at 450 milliseconds. This pulse times the rise of the 300VDC. If 300VDC does not reach 250VDC inthis time, the power supply shuts down on an error. The trailing edge of the pulse checks the 18VDC level from theScan Converter Power Supply. If this voltage is low or not present, the power supply shuts down on an error.

• the yellow CLK LED on PDB2 turns on

• the Programmable Power Supply activates

• the 3 power supplies synchronize

• the 150 Ohm bus load resistor is switched out of the supply line

• the normal system load takes over

gSoft Start CircuitrySoft start circuitry includes:

• soft start relay

• 30 Ohm 50 Watt resistor

• 5 Amp slow blow fuse

When the soft start relay is activated, the resistor and fuse (in series on isolation transformer input side) providePDB2 with surge protection at power-up. After the soft start relay switches main power into the isolation transformer,they are switched out. When the Soft Start Relay is activated, supply voltages are fed to the PDB2 circuit board.

Failure of resistor or fuse creates error #2 on the numeric LED.

Power-Down SequenceWhen the system powers down:

• the “Power Fail” signal goes low; the system backs up necessary data to the battery-backed RAM

• the +5VDC is held high for at least one second

• the Soft Start Assembly main power relay opens

• the 150 Ohm bus load resistor switches to discharge the 300VDC lines

gScan Converter

Power-up diagnosticsAt system power-up, the system runs a series of self-tests. If any self-test fails, the system generates a list of errorcodes by subassembly.

Note Tests vary by software level.Revision 27.x and above is currently the most common, due to Y2K upgrades.

Note A long list of error codes often indicates power supply problem.

See Error Codes for a list of error codes and related subassemblies.

gPower Supplies

GeneralA common indicator of a general power supply failure is a long string of power-up error codes.

Another indicator is an error code readout on the numeric LED in the power supply drawer.

Note If the numeric LED indicates a failure, there are usually other symptoms that indicate another problem,such as total system power-up failure.

Troubleshooting1) Find and measure the system output voltages. Begin by measuring the AC line voltage to ensure that the

system is receiving the proper power.

2) Examine and measure resistance of the power cord.

3) Check fuses in the power supply drawer. (See Theory of Operation for details.) Replace fuses as necessary.

4) Examine the power supply drawer. Under normal operating conditions, the drawer has only one activelyglowing LED: the PERCLK LED on the PDB2 board. Any other LED or lamp active indicates a failure.

5) Remove the load from the suspect power supply and test it again.

• If it functions, try sequentially loading the supply to determine which load is causing it to fail.

• If it does not function, replace it.
