    摘要： A magnet assembly for a Magnetic Resonance Imaging (MRI) system includes a vacuum vessel including an inner cylinder, an outer cylinder and a pair of tapered flanges connecting the inner and outer cylinders. The inner cylinder is made of a composite material. The outer cylinder and flanges are composed of several magnetic segments that provide a magnetic flux return path with low eddy currents. The segments are bonded together and electrically insulated from each other. A container, a thermal shield and a superconducting magnet coil assembly are disposed within the vacuum vessel. The superconducting magnet coil assembly includes a non-conductive cylindrical structure and superconducting coils. A thermally conductive cable is wrapped around the cylindrical structure and coils to form a thermally conductive envelope.

    摘要： A superconducting magnet is described and includes at least one superconducting coil, at least one support member coupled to the superconducting coil and at least one compliant interface between the superconducting coil and the support member. The superconducting coil defines a radial direction. The superconducting coil supports the superconducting coil along an axial direction that is substantially perpendicular to the radial direction. The compliant interface is configured to move along the radial direction when the superconducting magnet is energized.

    摘要： A superconducting magnet assembly is provided. The superconducting magnet assembly includes a superconducting magnet configured to generate a static magnetic field, an iron shield configured to shield the superconducting magnet, and a magnetic gradient coil assembly configured to generate a gradient magnetic field. The superconducting magnet assembly further includes one or more magnetic lamination elements disposed on the iron shield to reduce eddy current induced by the gradient magnetic field in the iron shield. A method is also presented.
