In order to perform imaging with water and fat separated in an efficient manner, a tomographic image is obtained having a phase GLIIHUHQFHRIŒEHWZHHQZDWHUDQGIDWXVLQJPDJQHWLFUHVRQDQFH Z WKHSKDVHRIWKHWRPRJUDSKLFLPDJHLVmultiplied by n (706), the phase after being corrected for wraparound is multiplied by 1/n (714, 716) and a phase image representing magnetic field inhomogeneity is generated. The tomographic image is corrected for phase using the phase image (718), and is separated into a water image and a fat image (726).
