The experiments performed showed
that the integrated RF/wireless coil was able to provide wireless Q-spoiling
during MR image acquisition without significantly impacting SNR or wireless
performance.
Figure 1: RF
currents flow on the integrated RF/wireless coil design for simultaneous MR
image acquisition (red) and wireless data transfer (orange), while a DC voltage
(blue) is applied to the PIN diode from a GPIO pin from the Wi-Fi transceiver module
for Q-spoiling.
Figure 3: Gradient-echo
EPI mean images, SNR maps of the mean images, and temporal SNR (TSNR) maps of
the image time series acquired in a water phantom, showing no degradation in
image quality for wireless Q-spoiling using the iRFW coil compared to
conventional wired Q-spoiling.
