An open MRI methodology and system that allows dynamic viewing and access to a patient. In intraoperative MRI, the MRI apparatus is configured in the shape of a typical operating room, with full 360° access to the patient. The MRI apparatus encompasses the entire operating room with magnets located on or near the ceiling and floor of the operating room. The remainder of the MRI apparatus, including the control computer, and imaging monitor, may be located outside of the MRI operating room, in order to keep the operating room free of unnecessary equipment, or located inside of the MRI operating room, as desired for operability of the MRI. The patient is placed over the magnet in the floor, the only fixed location in the operating room. The operating room may contain typical operating equipment, as needed, such as cardiopulmonary bypass units, surgical navigation systems, endoscopy systems, and anesthesia carts.
