A superconducting magnet coil support with cooling and a method for coil cooling are provided. One superconducting coil support arrangement includes a superconducting coil and at least one support beam supporting the superconducting coil and defining a tank for storing a cooling fluid therein. The superconducting coil support arrangement further includes a plurality of cooling tubes coupled to the superconducting coil and connected to the at least one support beam, wherein the plurality of cooling tubes are configured to transfer the cooling fluid therethrough.

Superconducting magnet coil support with cooling and method for coil-cooling

A gradient coil and an insert gradient coil for a magnetic resonance imaging system include a primary coil. The primary coil includes an upper primary coil portion and a lower primary coil portion, the lower primary coil portion being less curved in cross-section than the upper primary coil portion. The gradient coil also includes a shielding coil disposed outside of the primary coil. The shielding coil includes an upper shielding coil portion and a lower shielding coil portion, the lower shielding coil portion being less curved in cross-section than the upper shielding coil portion.

Flattened gradient coil for MRI systems

A magnet vent assembly for venting a cryogenic gas from a superconducting magnet of an MRI system. The assembly comprises: a first burst disc, the first burst disc comprising a first inlet and a first outlet; a second burst disc, the second burst disc comprising a second inlet coupled to the first inlet and a second outlet coupled to the first outlet; and wherein the magnet vent assembly is configured to switchably direct a flow path of cryogenic gas through either of the following: the first burst disc and the second burst disc. A service tool for a magnet vent assembly for venting a cryogenic gas from a superconducting magnet of an MRI system. The magnet vent assembly comprises a first burst disc. The service tool comprises: an inlet end, configured to be removeably attachable to an inlet flange of a magnet vent assembly; an outlet end, configured to be removeably attachable to an outlet flange of a magnet vent assembly; a second burst disc in operable communication with the inlet end and outlet end; and the service tool is configured to switchably direct a flow path of cryogenic gas through either of the following: the first burst disc and the second

Magnet vent assembly apparatus

A magnetic resonance imaging (MRI) device includes an inner gradient coil assembly proximate a patient positioning area, an outer gradient coil assembly proximate a magnet assembly, and a damping layer sandwiched between the inner and outer gradient coil assemblies.

Acoustically damped gradient coil

The present invention provides for a cooling system for circulating a coolant to cool the patient bore. In one embodiment, that patient bore consists of two concentric cylinders separated by spacers running either longitudinally or helically. In another embodiment of the present invention, fluid may be passed either helically or longitudinally through tubes bonded to the outer diameter of the patient bore such that the parts of the bore that are exposed to the patient are directly cooled. In a third embodiment, the RF coil could form part of the patient bore, with the helical or longitudinal fluid channels surrounding the patient bore.

Apparatus for active cooling of an MRI patient bore in cylindrical MRI systems

A super conducting magnet system for magnetic resonance systems comprising at least one radiation shield. Temperature sensors, an external refrigeration system and a controller are provided for maintaining said at least one shield at a constant temperature by heating the shield and reducing the heat provided as the refrigerator system wears or by increasing the frequency of the refrigeration cycle as the system wears or both.

Superconductive magnet for magnetic resonance systems

A support rod for supporting structures in a cryostat of a magnetic resonance system. The support rod has oppositely disposed stainless steel heads mounted on a glass reinforced plastic rod. The heads have threads on the main body thereof to minimize the length of the heads and thereby minimize heat condition.
