5-2-7 Signal flow overview (cont’d)
The MRX Board combines the functionality of the Receiver Boards (DRX and GRX) and the GFI.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.
