<p>In an MRI apparatus, an executing unit executes an image taking sequence according to a parallel imaging method so as to collect MR signals by using a plurality of RF coils; a reconstructing unit reconstructs an MR image from the MR signals; an unfolding processing unit performs an unfolding process to unfold aliasing that has occurred in the MR image, by using sensitivity distribution data indicating a spatial sensitivity distribution of the RF coils; a judging unit judges whether the unfolded image includes one or more pixels of which the pixel values are abnormal; and when the judgment result is in the affirmative, a correcting unit corrects the sensitivity distribution data so that the pixel values of the pixels become closer to a normal value. After the sensitivity distribution data has been corrected, the unfolding processing unit performs the unfolding process again by using the corrected sensitivity distribution data.</p> |
