Abstract
In one embodiment, an MRI apparatus includes a gradient generation circuit configured to apply a gradient pulse according to a pulse sequence in which application of an RF pulse and application of the gradient pulse are included; and an RF transmission circuit configured to (a) perform modulation on a controlled output waveform of the RF pulse in such a manner that the controlled output waveform of the RF pulse follows time variation of a magnetic resonance frequency caused by time variation of an eddy-current magnetic field estimated from a waveform of the gradient pulse and (b) apply the RF pulse subjected to the modulation to an object.
