1. An imaging apparatus, comprising:
a plurality of coils configured to capture imaging data from a scan of an object; and
circuitry configured to
segment, based on respective coil sensitivity maps for each of the plurality of coils, a region included in the imaging data into a first region that is affected by artifact due to motion of a first anatomical region of the object and a second region that is affected by artifact due to motion of a second anatomical region of the object to divide the imaging data into a first set corresponding to the first region and a second set corresponding to the second region, wherein the second anatomical region is different than the first anatomical region, the first anatomical region has a first motion pattern, and the second anatomical region has a second motion pattern different than the first motion pattern,
apply a first correction process to the first set, the first correction process being a process for correcting a motion of the first motion pattern of the object,
apply a second correction process to the second set, the second correction process being a process for correcting a motion of the second motion pattern of the object and being different than the first correction process, and
generate an image including the first anatomical region and the second anatomical region, the image being generated based on a result of the first correction process and the second correction process.
