Abstract
According to at least one of embodiments, a magnetic resonance imaging apparatus includes a superconducting magnet configured to generate a static magnetic field; a cryocooler configured to cool down the superconducting magnet in a refrigeration cycle in which mechanical fluctuation with a predetermined period is included; a sequence controller configured to acquire magnetic resonance signals for generating a diagnostic image from an object; and processing circuitry configured to correct phase fluctuation included in the magnetic resonance signals for generating a diagnostic image acquired by the sequence controller, the phase fluctuation being generated by periodic fluctuation of the static magnetic field caused by mechanical fluctuation of the cryocooler.
