<P>PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging apparatus shortening the time taken by imaging while correcting the non-uniformity of a static magnetic field, when imaging is performed while moving a subject. <P>SOLUTION: In a magnetic resonance imaging apparatus, before imaging, a measuring unit moves a couchtop on which a subject is placed to at least one position of a plurality of positions in an imaging space, adjusts shim coil current value supplied to the shim coil, and measures first shim coil current value when a static magnetic field is uniformized. On the basis of the first shim coil current value measured by the measuring unit, and subject information and an imaging condition, a calculator calculates unmeasured shim coil current value at one of the plurality of positions and at which the measuring unit has measured no shim coil current value. <P>COPYRIGHT: (C)2013,JPO&INPIT |
