Signal flow overview
The MRX Board combines the functionality of the Receiver Boards (DRX and GRX) and the GFI.
The Transmit Pulse bursts transmitted, are still routed from the GTX board(s) via the XD bus to the
Relay board where the ultrasound probes send the energy into the body. 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 MRX board. The MRX board amplifies the ultrasound signal and connects it with an A/D
converter to the digital domain. The digital signals are then further processed on the MRX boards.
All the processing is the same as a GFI configuration, but now the DRX, GRX and GFI are no longer
separate boards.
