We propose a digital wireless transceiver for a MRI coil with clock synchronization. We address the issue of phase rotation which can deteriorate the quality of image when a wireless transceiver of magnetic resonance signal is employed. Compared to EPI, spin warp sequences such as SE or FSE are more subject to the phase rotation. We developed a prototype in which clock signals in Rx coil side is synchronized to the system via a wireless link. Our experiment confirmed that the signal dynamic range is 50dB and phase rotation is 3deg/min, which indicates that this prototype is applicable to 2-D imaging using SE or FSE.
