Claim:
1. A magnetic resonance imaging apparatus comprising: an imaging unit detecting a nuclear magnetic resonance signal generated from an object after applying a high-frequency magnetic field and a gradient magnetic field to the object placed in a static magnetic field; a control unit controlling operation of the imaging unit; and an image processing unit performing calculation for the nuclear magnetic resonance signal and generating an image, wherein the control unit allows the imaging unit to execute predetermined preliminary imaging and main imaging, and the image processing unit includes: a frequency band calculation unit calculating a frequency band of phase components caused by inhomogeneity of the static magnetic field from the nuclear magnetic resonance signal obtained by the preliminary imaging; and an inhomogeneous static magnetic field elimination unit eliminating phase components in the frequency band from either of the nuclear magnetic resonance signal obtained by the main imaging or an image reconstructed from the nuclear magnetic resonance signal obtained by the main imaging.
