Abstract: According to one embodiment, a control device (30) of a magnetic resonance imaging apparatus (20A) includes a condition setting unit (100) and a judging unit (102). The condition setting unit sets an imaging sequence performed by the magnetic resonance imaging apparatus based on conditions of the imaging sequence. The judging unit calculates a value of electric current supplied to a gradient magnetic field coil (26) of the magnetic resonance imaging apparatus based on the conditions of the imaging sequence, calculates a value of voltage applied to the gradient magnetic field coil based on “a mutual inductance by which the gradient magnetic field coil causes mutual induction” so that electric current flowing the gradient magnetic field coil becomes equal to the value of electric current calculated, and judges whether the imaging sequence is practicable or not based on the value of voltage.

Abstract: According to one embodiment, an MRI apparatus (20) includes a first acquisition unit, a second acquisition unit and a correction unit (100). The first and second acquisition units produce a plurality of echo signals by performing echo signal acquisition sequence of EPI including application of a gradient magnetic field in a phase encoding direction, and acquire the plurality of echo signals as first and second template data, respectively. The second acquisition unit acquires the second template data under a sequence in which start timing of application of a gradient magnetic field in a readout direction is shifted from the case where acquisition of the first template data is performed. The correction unit (100) corrects phase error included in the echo signals by using the first and second template data.
