Abstract
In 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 having a number of wireless local coils and a wireless microwave transceiver array, one or more phase encoding steps are implemented to derive one or more magnetic resonance signals in the wireless coils. The signals from the phase encoding steps are upconverted to generate upper and lower sidebands of the magnetic resonance signals; and the upconverted upper and lower sideband signals are transmitted to the microwave array. Signals are derived from the upper and lower sidebands; and a representative phase difference between the signals derived from the upper and lower sidebands is determined from one or more of the phase encoding steps; then the representative phase difference is applied 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.
