Superconducting magnet with self-shield for whole body magnetic resonance imaging

The authors of this paper developed a superconducting magnet with self-shield for whole body magnetic resonance imaging (MRI) that features a magnetic field strength of 0.5 T, 1.0 T, and 1.5 T, and has the following characteristics: Low leakage magnetic field due to the directly mounted magnetic shield; very small in the 0.5 mT range. Reduced helium consumption due to the use of a high adiabatic cryostat and refrigerator; does not need liquid nitrogen. Horizontal service port reduces overhead clearance requirements. Superior mechanical strength; can even be transported in the cooled state. Fitted with an emergency run down unit
