1. A magnetic resonance imaging apparatus comprising
an imaging unit configured to acquire an image of a subject based on nuclear magnetic resonance and to perform a scout scan to acquire a scout image; and
an imaging position determination unit configured to calculate an imaging range of the subject and determine an imaging position, wherein
the imaging position determination unit uses the scout image, acquired by the imaging unit, to calculate multiple imaging ranges including a minimum imaging range that embraces a predetermined tissue, and a maximum imaging range that embraces a range in which the tissue is displaced within a cycle of a periodic motion, and determines any of the multiple imaging ranges as the imaging position for a main scan according to imaging conditions, the imaging conditions including whether a breathing method of the main scan is natural breathing or breath holding.
