Abstract
According to one embodiment, a magnetic resonance imaging apparatus includes amplifiers, processing circuitry, and a power supplier. The amplifiers supplies power for each of a plurality of channels of gradient coils. The processing circuitry obtains, for each of the channels, a voltage gradient that represents a temporal change of a power supply voltage for supplying a current to the amplifiers. The power supplier supplies the power to an amplifier corresponding to a specific one of the channels on a priority basis in accordance with the voltage gradient.
