Abstract

According to one embodiment, a magnetic resonance imaging apparatus includes processing circuitry. The processing circuitry calculates inverse characteristics of a Bsensitivity map in an imaging area of a subject. The processing circuitry fits a multi-degree polynomial function to the inverse characteristics of the Bsensitivity map. The processing circuitry calculates positions in k-space, amplitudes and phases of a plurality of RF pulses by associating the polynomial function fit to the inverse characteristics with a relational expression between the RF pulses and k-space. The processing circuitry controls application of the RF pulses in accordance with the positions, the amplitudes and the phases. The polynomial function and the relational expression have equal degrees.
