摘要： A magnetic resonance imaging system has a superconducting magnet housed within a cryostat, a cryogenic refrigerator that cools within the cryostat, a helium compressor that supplies compressed helium to the cryogenic refrigerator and to receive a return flow of compressed helium from the refrigerator, and a magnet supervisory system controlling operation of the magnet resonance imaging system. An apparatus is provided for controlling the speed and/or timing of operation of the helium compressor in accordance with predefined algorithms in response to system state data.

摘要： A magnet assembly has a number of axially-aligned coils, the radial mid-point of each coil being axially-aligned with a portion of a radial extent of an adjacent coil in the assembly. Compression blocks are provided between adjacent coils at circumferential intervals, to retain the coils in fixed relative positions.

摘要： A method for assembling a cylindrical magnet assembly, which includes at least one coil mounted on a former, to a bore tube is provided. The method involves providing a cavity in the former at selected locations. At each of the selected locations, the material of the bore tube is deformed to form a radially-directed protrusion. Each protrusion is brought to bear against a periphery of each corresponding cavity.

摘要： A magnetic resonance imaging system has a superconducting magnet contained within a cryostat, the cryostat being cooled by a cooling system that includes a healing and compressor, a refrigeration device and a local supervisory system. The helium compressor provides compressed helium to the refrigeration device, and the local supervisory system controls operation of the refrigeration device. The helium compressor is in communication with the local supervisory system, and also is able to communicate, independently of the local supervisory system, with a remote service provider.
