Abstract
A magnetic resonance imaging apparatus according to an embodiment includes a transmission channel, a first phase shifter, and a second phase shifter. The transmission channel is configured to arrange, in at least a partial section between a generator and a transmitter coil, radio frequency (RF) pulse signals to be transmitted parallel to one another via a plurality of channels. The first phase shifter is configured to shift at least one of phases of the RF pulse signals to be transmitted via the channels, so that the phases of the RF pulse signals are in a relationship of being different from one another. The second phase shifter is configured to shift, in accordance with a phase amount shifted by the first phase shifter, at least one of phases of the RF pulse signals at a stage prior to inputting the RE pulse signals to the transmitter coil.
