Demodulator Board

APIO Board

Physio Module Option

The demodulator board performs image and Doppler demodulation for BMode, MMode, PW and CW phased and non-imaging Doppler modes, and color flow mode. It sends a baseband data stream to the BPAP board.

The demodulator board contains the following:

Digital filters and mixers for demodulating 2D, color flow, and PW RF data

The independent transducer CW Doppler electronics and steerable CW detector functions

The 120 MHz system clock. The clock signal is distributed to the TR and BPAP boards.

Circuitry that generates TGC signals

The acoustic processor I/O (APIO) board is the token ring interface between the system’s PC and the e-box. The APIO board also handles input from the foot switch’s three control buttons (via the I/O panel) and forwards them to the PC. The board also generates trigger signals for legacy printers.

The board handles these signals from the PC:

The R-wave pulse from the physio module that it sends to the BPAP board

The DC on-off bit that it sends to the power supply

Commands that program the BPAP board at startup

Acoustic data from the BPAP board for the acoustic imaging display

The self-contained Physio module resides in one of the PC’s drive bays. The module receives power from the drive bay’s power connector, but it communicates with the system through a USB cable to the PC’s motherboard. A shielded and grounded enclosure prevents electromagnetic interference. See Figure 4-3on page 51 for a detailed representation of the module’s functions and connections.
