Abstract

A magnetic resonance imaging apparatus according to an embodiment includes a static magnetic field magnet, an amplifier circuit, a phase control circuit, and an RF coil. The static magnetic field magnet is configured to generate a static magnetic field in a bore. The amplifier circuit is configured to amplify an input signal. The phase control circuit is configured to control a phase of a signal amplified by the amplifier circuit on a basis of gain of the amplifier circuit obtained from a signal inputted to the amplifier circuit and a signal amplified by the amplifier circuit, and on a basis of a reference gain. The RF coil is configured to transmit, to a subject placed in the bore, an RF pulse based on a signal amplified by the amplifier circuit and whose phase is controlled by the phase control circuit.
