ABSTRACT:
In a magnetic resonance apparatus, motion artifacts in data obtained are reduced by transmitting, during data collection, an r.f. signal of known amplitude and of a frequency different from that of the spins excited for imaging, and utilizing a signal induced by that r.f. signal in a coil (45A,45B) positioned adjacent the data signal detector means (10A,10B) to effect an alteration of the signal produced by the detector means (10A,10B) such as to reduce the motion artifacts.
