Abstract
According to one embodiment, an MRI apparatus includes an amplifier and processing circuitry. The amplifier amplifies an RF pulse and outputs the amplified RF pulse to an RF coil. The processing circuitry performs correction processing on an envelope of an RF pulse to be inputted to the amplifier so as to compensate nonlinear input-output characteristics of the amplifier. As to this correction processing, the processing circuitry selects a correction information item out of a plurality of correction information items prepared for a corresponding plurality of imaging conditions and performs the correction processing by using the selected information item.
