摘要： A trailer for housing a mobile MRI system has magnetic shielding in the form of a plurality of sheets of magnetic material which are supported within the trailer, by a rigid supporting structure or frame. The layers are arranged in a stacked or laminar configuration with the laterally longest layer disposed inward of the remaining layers, such that the width of the gap between that layer and the exterior walls of the trailer at the lateral extremities of the shielding is greater than its width in a central area. The rigid frame maintains the gap and prevents contacting of the shielding and the trailer walls.

摘要： 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.

摘要： 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.
