4 Principle Diagram of TR Board
The principle diagram of TR board is shown above, the main functions include:
 Transmitting: in accomplishing the transmitting focus of the entire unit, TR_FPGA controls 64
channels on a single board to send high-voltage ultrasound signal to the probe.
 Receiving: in accomplishing the receiving focus, TR_FPGA controls 64 channels on a single
board to receive ultrasound echo signal of the probe.
 Assemble CW function.
 It refers to the CW mini board on TRB board; it fulfills the filtering and sampling of adjustment of
CW, and accomplishes the reception of CW signal.
