Abstract
In one embodiment, an MRI apparatus includes: a current-driven magnet configured to generate a magnetic field that predominantly determine a magnetic resonance frequency; a detector configured to detect a position of an object to be imaged in a movable state in the magnetic field; and control circuitry configured to set an imaging region of the object depending on a motion of the object by controlling a drive current of the current-driven magnet based on the detected position of the object.
