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.
