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.

Abstract: A magnetic resonance imaging device according to an embodiment includes a processing circuitry. The processing circuitry obtains, from an image of a test subject taken by an optical photographing device, image-related information regarding at least either the test subject or a radio frequency (RF) coil attached to the test subject. Then, the processing circuitry selects statistical information about the attachment position of the RF coil based on the image-related information. Subsequently, the processing circuitry outputs the attachment position of the RF coil corresponding to the statistical information.
