Abstract: A superconducting magnet system is provided. The superconducting magnet system includes a coil former, superconducting coils supported by the coil former, and one or more cooling assemblies. The cooling assemblies are in thermal contact with the coil former and include one or more cooling tubes for receiving a cryogen passed therethrough. The cooling assemblies are detachably mounted on the coil former and form at least one cooling circuit therein. The cooling assemblies include one or more flat surfaces attached on a surface of the coil former. A method of manufacturing the same is also provided.

Abstract: An imaging device may include a patient bore to house a subject to be imaged, wherein the patient bore includes one or more bore tubes. The imaging device may also include a gradient coil surrounding, at least partially, the patient bore and a radio frequency (RF) shield located outside the one or more bore tubes. Additionally, the imaging device may include an RF coil located within at least one of the bore tubes.

Abstract: A magnetic resonance imaging system includes at least one gradient coil, at least one coil former, a thermal shield assembly, and at least one linking member. The at least one gradient coil generates at least one gradient field along at least one direction in response to pulsed signals. The at least one coil former is attached with at least one coil. The thermal shield assembly is arranged adjacent to the at least one coil former. The at least one linking member is configured for increasing mechanical rigidity of the thermal shield assembly by mechanically linking at least a part of the thermal shield assembly with the at least one coil former. As a result, mechanical vibrations of the thermal shield assembly can be reduced.
