Abstract
According to one embodiment, an MRI apparatus includes an amplifier and a control circuit. The amplifier amplifies an RF pulse and supplies it to an RF coil. The control circuit is configured to determine whether an output RF pulse outputted from the amplifier is fed back to an input side of the amplifier to correct an input RF pulse to be inputted into the amplifier, based on a determination value being set according to a slew rate of the input RF pulse.
