Abstract
A magnet apparatus for use in magnetic resonance imaging systems comprises a superconducting coil which produces a main magnetic field in a working volume defined in the bore in which a patient is accommodated and a cryostat accommodating the superconducting coil and keeping the superconducting coil in the superconducting state. This cryostat includes only one thermal radiation shield and is configured with a smaller volume than that of conventional cryostats with no reduction in the heat insulation effects. Therefore, the dimensions of the bore are determined to comply with 1.0.ltoreq.L/B<1.9 where L is the length along the Z axis of the bore and B is its diameter. Thus, the length L along the Z axis of the bore is determined to be relatively short while the dimensions of the working volume necessary for diagnosis is secured in the bore, with the result that the oppressive sensation that the patient has in the bore is lessened.
