| titleOfInvention | A Housing for a Magnetic Resonance Imaging Scanner which Includes a Ferrous Closure Member |
| abstract | A superconducting magnet housing includes an outer vacuum vessel 6 housing a radiation shield 4 and a coolant vessel 2 containing coolant 3. Pumping-out of the superconducting magnet housing is facilitated by providing a hole 8 through the radiation shield 4 to a pump-out port 7. To reduce radiation of heat via this hole to an inner coolant containing vessel 2 a closure member 9 is provided. The closure member is provided with a ferrous constituent or member which is then attracted inwards during initialization of the superconducting magnet 1. This draws the closure member into engagement with the shield to close the hole and to prevent radiation of heat therethrough. The closure member may be held in spaced apart relationship during pump down by clips 10, and these may be profiled to maintain the abutment of the closure member over the hole. The superconducting magnet housing arrangement may be part of an MRI scanner apparatus. |
