Abstract: An MR imaging method wherein motion of an object to be imaged is examined during a preparation phase preceding the actual MR examination. The necessary sequences for the subsequent MR examination are modified during the examination to compensate for the motion based on motion parameters calculated during the preparation phase or motion parameters derived from the motion parameters calculated during the preparation phase based on a correlation between the motion parameters.

Abstract: A continuous moving table magnetic imaging method is proposed where a 'lateral' read out is performed that is transverse to the direction of motion. This magnetic resonance imaging method for imaging a moving object includes spatially selective RF excitations are applied for respective phase-encodings. The sub-volume is excited by the spatially selective RF excitation moves with the motion of the object for respective subsets of primary phase-encodings. Acquisition of magnetic resonance signals is performed from a three-dimensional sub- volume of the object. The magnetic resonance signals are read encoded in a direction transverse to the direction of motion of the object and phase-encoded in at least the direction of motion of the object.
