Data amounts of massive parallel receiver arrays as well as latency requirements of real-time applications such as interventional MRI, navigators etc. prompt for high-speed data preprocessing. First steps in the reconstruction such as noise pre-whitening or channel combinations and compressions can be efficiently performed on FPGAs. Here we present a flexible system and software architecture for such tasks and demonstrate its capability performing real-time coil compression directly in the spectrometer.
