Abstract: A magnetic resonance imaging apparatus according to an embodiment includes a transmission coil and processing circuitry. The transmission coil is configured to apply a high frequency magnetic field to an object. The processing circuitry is configured to: derive, based on at least one of an imaging region and the body shape data of the object, a specific area in a field of view (FOV); and determine, based on a signal within the specific area, an output power level of a high frequency pulse signal supplied to the transmission coil.
