20090261830 | MAGNETIC RESONANCE IMAGING SCANNER - A processor is provided in a MRI scanner which senses pressure within a cryogen vessel and the ambient environmental pressure outside of the scanner. It controls a pressure controller means in the cryogen to in turn control the pressure to ensure that it is set to provide as large a buffer as possible before a pressure relief valve is opened. This ensures that cryogen is not lost unnecessarily. | 10-22-2009 |

20090184714 | HOUSING FOR A MAGNETIC RESONANCE IMAGING SCANNER AND A SCANNER - Pumping out of a vacuum vessel and housing of a scanner is facilitated by providing a hole through a radiation shield. To reduce radiation of heat via this hole to an inner coolant containing vessel a closure member is provided. This is held in spaced apart relationship during pump down by clips. The closure member is provided with a ferrous constituent or member which is then attracted inwards during initialization of the superconducting. This draws the closure member into engagement with the shield to close the hole and to prevent radiation thereby. The clips are profiled to maintain the abutment of the closure member over the hole. | 07-23-2009 |
20090188261 | Limiter for Limiting the Motion of Components in a Cryostat - A limiter is provided to limit the motion of components in a cryostat during transit. This permits the use of a support structure which minimises the disturbance to an insulating structure and thus reduces ingress of heat to the cryogen. Cryogen loss is reduced leading to lower operating costs. | 07-30-2009 |
20090193816 | Method and Apparatus for Controlling the Cooling Power of a Cryogenic Refrigerator Delivered to a Cryogen Vessel - The present invention provides a cryostat comprising a cryogen vessel ( | 08-06-2009 |
20100038131 | Current Leadthrough for Cryostat - A current lead-through for providing an electrically conductive path between an interior of a vessel and the exterior of the vessel. The electrically conductive path is electrically isolated from the material of the vessel. The current lead-through comprises an electrically conductive pin surrounded by an electrically isolating sealing material, and retained within a tubular carrier body by the sealing material, the electrically conductive pin being exposed at each end of the tubular carrier body to enable electrical connection thereto. | 02-18-2010 |

20090009170 | HIGH-MAGNETIC FIELD MRI SYSTEM WITHIN A HOUSING AND A METHOD OF OPERATING AN MRI SYSTEM WITHIN A HOUSING - An MRI system is housed within a housing that is provided with a set of deployable barriers that are attachable to the housing. The magnet in the MRI system may be operated at a first magnetic field intensity, such that the magnetic field outside of the housing remains below a safety limit when the barriers are not deployed. The magnet in the MRI system may be operated at a second magnetic field intensity, higher than the first, when the barriers are deployed, such that the magnetic field outside of the barriers remains below the safety limit. | 01-08-2009 |
20090193818 | Apparatus for Improved Precooling of a Thermal Radiation Shield in a Cryostat - A cryostat comprises a cryogen vessel housed within an outer vacuum container (OVC), a thermal radiation shield being located between an external surface of the cryogen vessel and an internal surface of the OVC. A decouplable thermal link arrangement is provided between an external surface of the cryogen vessel and an internal surface of the thermal radiation shield, being decoupled by action of an applied magnetic field. | 08-06-2009 |
20100041976 | CRYOSTAT FOR REDUCED CRYOGEN CONSUMPTION - A cryostat has a cryogen vessel retained within an outer vacuum container, a thermally insulating jacket surrounding the outer vacuum container and insulating it from ambient temperature. | 02-18-2010 |
