Abstract
To supply a magnetic resonance imaging (MRI) apparatus capable of shifting a high frequency of noise into a low frequency during measurement, the magnetic resonance imaging apparatus includes: a gradient magnetic field device () that applies a pulse-shaped gradient magnetic field to an object placed in a static magnetic field; and a measurement control unit () that drives the gradient magnetic field device by a gradient magnetic field pulse and measures magnetic resonance image data. The measurement control unit performs noise suppression control to shift a frequency of noise generated by the gradient magnetic field device to a low frequency side by changing a waveform of the gradient magnetic field pulse during repetition of the gradient magnetic field pulses at a constant period.
