Abstract
To acquire a more accurate tissue contrast image such as a water-fat separation image in time-series imaging by an MRI apparatus, a static magnetic field non-uniformity map is created from a plurality of echo signals having different TEs obtained in time series, and a water-fat separation image is obtained using the static magnetic field non-uniformity map. Processing (spatial direction discontinuity correction processing) for correcting discontinuity of a phase or a frequency in a spatial direction and processing (time-series direction discontinuity correction processing) for correcting discontinuity in a time-series direction are performed for the static magnetic field non-uniformity map.
