The increasing need for RF acquisition channel counts
from receiver coil arrays but also applications such as
field monitoring, RF safety surveillance of parallel
transmit systems and other applications make cable
routing and its implications for patient comfort, system
handling and safety a cumbersome task. Further
ultra-high field system push the frequency span of which
the receiver has to be able to operate with. A novel
platform is presented with broadband sampling ADCs
communicating via digital high speed optical links to a
host. It was found that the performance of rack mounted
system can be matched at tolerable power consumptions.
