Abstract:
1. A magnetic resonance imaging apparatus comprising: a static magnetic field generator configured to generate a static magnetic field in an imaging space; a shim coil unit configured to generate a correction magnetic field that corrects non-uniformity of the static magnetic field; a measuring unit configured to move a couchtop on which a subject is placed to a first position in the imaging space, and measure at least one first shim coil current value corresponding to the first position; a calculator configured to calculate, on the basis of the at least one first shim coil current value and at least one of subject information and an imaging condition, at least one second shim coil current value corresponding to a second position in the imaging space; and a controller configured to perform imaging, when the couchtop is placed at the second position, while uniformizing the static magnetic field by supplying the shim coil unit with the at least one second shim coil current value.
