Abstract

Provided are an apparatus and a method for appropriately correcting a sensitivity of a composite image obtained by HiMAR imaging in which a plurality of times of imaging are performed with different frequency bands. An image processing unit of an MRI apparatus includes a sensitivity correction unit that performs sensitivity correction on a composite image obtained by HiMAR imaging. The sensitivity correction unit separates sensitivity data for each bin from image data for each bin, and combines the sensitivity data for each bin to obtain a sensitivity distribution. The sensitivity distribution for each bin is obtained by dividing an image in which the sensitivity distributions of the respective channels are combined, by an image in which the sensitivity distributions do not exist. The composite image of all bins is corrected by using this composite sensitivity distribution.
