Patent ID: 7417429

Claim:
A magnetic resonance imaging method for forming an image of a region of a patient that is larger than a restricted homogeneity region of a main magnet field of a magnetic resonance imaging apparatus from a plurality of parallel imaging signals sampled in the restricted homogeneity region, the method comprising: continuously moving a patient through the restricted homogeneity region of the main magnet field; exciting spins in an area of the patient in the restricted homogeneity region with an excitation profile as the patient moves through the main magnetic field, undersampling resonance data in the restricted homogeneity region with parallel receiver antennae which each have a sensitivity pattern as the patient moves through the main magnet field to define a block of measurements contiguous in time having preserved magnetisation and presaturation conditions within the excited region of the patient; and generating the image of the region of the patient that is larger than the restricted homogeneity region including unfolding fold-over artifacts due to the undersampling using (a) the sensitivity patterns of the receiver antennae and (b) at least one of: the excitation profile, a magnetization and presaturation profile, and a frequency-response pattern of a receiver.
