In one embodiment, an MRI system includes at least one magnetic field assembly and at least one image generator. The at least one magnetic field assembly includes an open main magnet configured to generate a main magnetic field for dominantly determining a magnetic resonance frequency, a gradient coil configured to generate a gradient magnetic field, and an RF coil configured to generate a radio frequency magnetic field. The at least one image generator is configured to generate a magnetic resonance image of an object by using the main magnetic field, the gradient magnetic field, and the radio frequency magnetic field generated by the at least one magnetic field assembly. The main magnet is disposed between adjacent examination rooms. The main magnetic field generated by the open main magnet is commonly used in each of the adjacent examination rooms.

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.
