MAGNETIC RESONANCE IMAGING APPARATUS AND IMAGE PROCESSING APPARATUS

摘要

A magnetic resonance imaging apparatus according to an embodiment includes a collector, a transformation module, an unfolding module and an inverse transformation module. The collector collects time-series k-space data of a plurality of channels while spatially changing a sampling position. The transformation module obtains transformed space data of the respective channels by applying, to the time-series k-space data of the respect channels, Fourier transform on a spatial axis and certain transformation on a temporal axis. The unfolding module eliminates a signal point on a basis of a certain criterion and performs unfolding using the transformed space data on the respective channels and sensitivity distribution information on the respective channels; and the inverse transformation module applies inverse transformation of the certain transformation on the temporal axis to an unfolded data on which the signal point has been eliminated and the unfolding has been performed.
