Weak ultrasound echoes from body structures and blood cells are received by the probes and routed
via the Relay board and the XD bus to the RX board. The RX board amplifies these signals. Then the
signals are routed to the DRX board(s) where the signals are A/D converted. The digital signals are then
further processed on the DRX boards.
