Abstract: A magnetic resonance apparatus configured to select a coil mode that includes a combination of coil elements to be used when a subject is scanned from within a plurality of coil elements and configured to execute a predetermined scan for acquiring data on the subject using the selected coil mode is provided. The magnetic resonance apparatus includes a coil device having n coil modes, a selecting unit configured to select, from within the n coil modes, a candidate for the selected coil mode, a scanning unit configured to execute a first scan for acquiring the data on the subject using the candidate, and a sensitivity map preparing unit configured to prepare a sensitivity map of the candidate based on data obtained by the first scan.

Abstract: 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.

Abstract: 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.
