Magnetic resonance imaging apparatus and method of supporting setting of imaging condition thereof

A magnetic resonance imaging apparatus comprising:

• an imaging unit including a magnet that generates a uniform static magnetic field, a transmission coil that applies a high-frequency magnetic field to a subject placed in the static magnetic field, a reception coil that has a plurality of elements and receives a nuclear magnetic resonance signal generated from the subject, and a gradient magnetic field coil for adding spatial information to the nuclear magnetic resonance signal;
• and
• a computer including a reconstruction unit that reconstructs an image by using the nuclear magnetic resonance signal, and an imaging condition setting unit that sets an imaging condition including at least a FOV as a condition for imaging performed by the imaging unit,
• wherein the computer further includes
• an aliasing signal range estimation unit that estimates a spatial range in which an aliasing signal from a phase encoding direction occurs, based on the FOV set as the imaging condition,
• a determination unit that determines whether or not it is necessary to perform a change of the imaging condition, which includes at least one of a change of the FOV or a change of a weight of each channel constituting the reception coil, based on an estimation result of the aliasing signal range estimation unit,
• a FOV change unit that decides a range of the FOV to be changed, based on a determination result of the determination unit and the estimation result of the aliasing signal range estimation unit, and
• a channel weighting amount calculation unit that calculates a weighting amount of each channel constituting the reception coil, based on the determination result of the determination unit and the estimation result of the aliasing signal range estimation unit, and
• in a case where the imaging condition is changed, the imaging condition setting unit changes a set imaging condition to the changed imaging condition.
