Patent ID: 8396277

Claim:
A magnetic resonance imaging apparatus comprising: an executing unit that executes an image taking sequence according to a parallel imaging method so as to collect magnetic resonance signals by using a plurality of radio frequency coils; a reconstructing unit that reconstructs a magnetic resonance image from the magnetic resonance signals; an unfolding processing unit that performs an unfolding process so as to unfold aliasing that has occurred in the magnetic resonance image, by using sensitivity distribution data indicating a spatial sensitivity distribution of the radio frequency coils; a judging unit that judges whether the unfolded image obtained as a result of the unfolding process includes one or more pixels of which pixel values are abnormal; and a correcting unit that, in a case where the judging unit has judged that the unfolded image includes one or more pixels of which the pixel values are abnormal, corrects the sensitivity distribution data in such a manner that the pixel values of the pixels become closer to a normal value, wherein after the sensitivity distribution data has been corrected, the unfolding processing unit performs the unfolding process again by using the sensitivity distribution data that has been corrected.
