Parallel MRI acquisitions are generally reconstructed off-line on PCs and computer clusters. Building upon an existing multichannel digital receiver, we present an innovative single-FPGA front-end that performs real-time 2D-FFT reconstruction from arrays of up to 16 coils. Partial reconfiguration enables rapid switching of FPGA modules for maximal flexibility and lower hardware cost. After an acquisition has been buffered, more complicated parallel MRI reconstruction techniques can replacedoi:10.1109/acssc.2006.355084 fatcat:7rjtrw25sjfgpmgtxx5dw36uci
