Fig 2 Schematic Diagram of Ultrasound System Front-end
Front-end unit mainly consists of:
 Probe board
 TR_A board, TR_B board, TR_C board
 Engine board
 CW sub-board (option configuration on the TR_A and TR_C board, standard configuration on
the TR_B board)
 4D-TEE board
 ECG module
 Pencil probe board (optional)
Ultrasound front-end unit carries out the transmitting and receiving, the ultrasound image
signal will be sent to the CPU module on the digital board for post processing after amplification,
A/D conversion, beam forming and signal processing.
