If
wireless patient coils could be realized, they would reduce setup time and reduce worry about the liability of the connectors on coils. Battery powering these coils would limit scan
time, so it is desirable to use wireless power transfer (WPT), which uses inductively
coupled resonant coils to transmit and receive power at a particular frequency.
With RF gating, imaging
while receiving up to 11W is demonstrated and shown to have minimal impact on
image quality.
