Patent ID: 8217656

Claim:
A method of compensating for the effects of motion of an image subject during magnetic resonance imaging using phase encoding in a magnetic resonance imaging system comprising a plurality of wireless local coils and a wireless microwave transceiver array; the method comprising: carrying out one or more phase encoding steps to derive one or more magnetic resonance signals in the wireless coils; upconverting the signals from the phase encoding steps to generate upper and lower sidebands of the magnetic resonance signals; transmitting the upconverted upper and lower sideband signals to the microwave array; deriving signals from the upper and lower sidebands; determining a representative phase difference between the signals derived from the upper and lower sidebands from one or more of the phase encoding steps; applying the representative phase difference to each pair of derived signals for every phase encoding step to produce phase compensated signal pairs; such that the pair of signals are moved more closely into phase.
