According to one embodiment, a magnetic resonance imaging apparatus includes processing circuitry and sequence control circuitry. The processing circuitry specifies a position of an imaging target of a subject in a bore, using an image collected by a first imaging protocol. The processing circuitry determines, in accordance with the specified position, a correction value for a phase of an RF pulse and/or a correction value for an amplitude of the RF pulse, the RF pulse being related to a transmit RF wave, so that non-uniformity in a magnetic field of the transmit RF wave transmitted to the imaging target can be corrected. The sequence control circuitry executes a second imaging protocol for the subject, using the determined correction value.
