Abstract
A magnetic resonance imaging apparatus according to an embodiment includes a sequence control unit that controls a gradient magnetic field power supply, thereby performing a pulse sequence including the application of a continuous readout gradient magnetic field pulse. The sequence control unit controls the gradient magnetic field power supply such that the slew rate of the gradient magnetic field pulse is reduced in stages as the output voltage of a gradient magnetic field amplifier is reduced in stages.
