Abstract:
1. A superconducting gradient coil module configured for cryogenic cooling, comprising: a vacuum thermal isolation housing comprising a double wall hermetically sealed jacket that (i) encloses a hermetically sealed interior space under a vacuum condition, and (ii) substantially encloses an interior chamber region that is separate from the hermetically sealed interior space and is configured to be evacuated to a vacuum condition; at least one superconductor gradient coil disposed in said interior chamber region and configured for generating one or more magnetic field gradients for at least one of magnetic resonance imaging and magnetic resonance spectroscopy; a thermal sink member disposed in said interior chamber region and in thermal contact with said at least one superconductor gradient coil; and a port configured for cryogenically cooling at least the thermal sink member.
