摘要:
A magnetic resonance imaging apparatus has a storage unit and a processing unit. The storage unit stores correction data of a position coordinate, in which the position coordinate in the reconstruction FOV is caused to correspond to a position coordinate in a display FOV included in the reconstruction FOV based on an intensity of a gradient magnetic field. If both of a first position coordinate and a second position coordinate, which is further from the center of the reconstruction FOV, correspond to same position coordinate in the display FOV, the correction data is data for causing only the first position coordinate to correspond to the position coordinate in the display FOV. The processing unit corrects a reconstructed image based on the correction data and obtains an image of the display FOV.
