In this work, we demonstrate wireless Q-spoiling of an MRI surface coil in a 1.5T scan using commercial Linx LR series modules. These modules send a digital data stream wirelessly using an On-Off-Keying (OOK) protocol and a carrier frequency of 418MHz. With the simple Linx modules for wireless scanner state detection, it becomes possible to perform tasks such as wirelessly Q-spoiling MRI receive coils and beginning readout of receive coil data. Such steps are necessary for the ultimate goal of wireless MRI.
