摘要：
A magnetic resonance imaging apparatus includes a collector which collects magnetic resonance signals emitted from a region of interest of a subject, and a correction magnetic field generator which generates a correction magnetic field to correct the nonuniformity of a static magnetic field on the basis of magnetic resonance signals which are contained in the magnetic resonance signals collected by the collector, are emitted from a specific region which forms a portion of the region of interest.
