Abstract: In one aspect, a magnetic resonance imaging (MRI) device includes a non-magnetic, thermally conductive spreader substrate having a broken metal layer coupled to a thermally conductive, electrically non-conductive layer, wherein the broken metal layer is configured to exchange heat with at least one serpentine cooling tube.

Abstract: A cryogenically cooled radiofrequency (RF) coil structure for use in Magnetic Resonance Imaging (MRI) and method for cryogenically cooling RF coils are provided. The cryogenically cooled RF coil structure comprises a sealed structure constructed of non-conducting material and adapted for containing a cooling substance and at least one RF coil disposed integrally in contact with the sealed structure such that sealed structure and integrally disposed RF coil are disposed about an object to be imaged.

Abstract: In one aspect, the present invention is a cooling assembly for an electrical component. The assembly includes a non-magnetic, thermally conducting spreader substrate, and at least one serpentine cooling tube disposed on and in thermal contact with the thermally conducting spreader substrate so that said substrate is cooled when the one or more serpentine cooling tubes are operating.
