Abstract
A magnetic resonance imaging apparatus includes a scan section for executing a navigator sequence which transmits an RF pulse to a subject to obtain each magnetic resonance signal as navigator data. Upon execution of the navigator sequence, the scan section excites both a navigator area having two regions from which intensities of different navigator data signals are obtained, the two regions containing a body-moved region of the subject, and a region different from the two regions simultaneously, and transmits the RF pulse in such a manner that the phase of navigator data obtained from the different region differs from the phase of at least one region of navigator data obtained from the two regions.
