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.
