摘要： A magnetic resonance imaging apparatus executes a calibration scan for acquiring calibration data used to correct image data of a subject and an imaging scan for acquiring the image data of the subject and receives magnetic resonance signals using combinations of coil elements selected out of a plurality of coil elements. The magnetic resonance imaging apparatus includes a calibration scan condition determining device for determining a scan condition for the calibration scan, based on a first scan range of the subject taken when the imaging scan is executed and a first combination of coil elements used to receive magnetic resonance signals in the first scan range.

摘要： The invention is intended to obtain optimal shim values even if slice planes are slanted with respect to the system-inherent coordinate system. The section for setting a plane for calculating shim values sets planes perpendicular to and a plane parallel with a slice plane in a system of coordinates x′, y′, and z′ perpendicular to the slice plane. The section for calculating shim values obtains shim values with regard to this slice plane in this coordinate system, based on data acquired by the data acquiring section. The coordinates converting section converts the thus obtained shim values to shim values in the system-inherent x-y-z coordinate system of the MRI apparatus.
