GE OPTIMA MR360 Service Training page 95

This block diagram shows RF receive chain in SV system. If the system configuration is
MR360 without Express coil, J22 in Mega Switch has no cable connection.
Mega Switch selects different input signal from Port A coil, PA coil and body coil, and
amplifies the selected signal, and converts them to intermediate frequency signal, which
center frequency is about 16MHz.
Then, RRX gets the eight channel RF signals and digitizes them with ADC, and converts them
to optical signal, and send to VRF in VRE via VRF Data Link.
VRF converts the optical signal to electrical signal and filters them, then sends them to ICN
for image reconstruction.
Then the reconstructed image is send to host via Ethernet switch.
