The operation of 60GHz data transmission inside the MR room using the WiGig standard has been demonstrated in a previous study. It offers an off-the-shelf solution for reliable, high-speed data transmission as required by modern high-channel-count array coils. However, wireless data transmission is only one component of a complete receiver chain in MRI. Since the ARM-based platform employed in our previous study is not powerful enough to implement full high-speed high-fidelity acquisitions, we propose to connect the WiGig data link with a FPGA board, clock generator board and a high-precision ADC board to increase the speed and the fidelity.
