Abstract
A magnetic resonance imaging apparatus capable of measuring a temperature increase due to an application of RF magnetic fields for data acquisition purpose, and notifying an information on the measured temperature increase regularly to an operator, so as to secure the safety of a body to be examined. In this magnetic resonance imaging apparatus, the image data acquisition operation is controlled to acquire a phase information associated with a temperature change in an interior of the body to be examined, by displacing either an observation start timing or a radio frequency magnetic field application timing for a prescribed magnetic resonance signal in the magnetic resonance signal sequence from a normal timing for acquiring image data.
