Abstract
A magnetic resonance imaging apparatus executes scans for executing a navigator sequence for acquiring as navigator data a magnetic resonance signal from a navigator area containing tissues body-moved in a subject and executing an imaging sequence for acquiring a magnetic resonance signal from an imaging area as imaging data at the subject, thereby to generate an image with respect to the imaging area. The magnetic resonance imaging apparatus includes, a phase profile generating part which generates a phase profile so as to show a relationship between a phase of the navigator data and a position of the navigator area, a phase correcting part which corrects folding back of the phase profile generated by the phase profile generating part, and a position detecting part which detects a position of a tissue body-moved in the navigator area, based on the phase profile corrected by the phase correcting part.
