Device for active cooling of an mri - patient tunnel in the case of cylindrical mri - systems

摘要

Patient tunnel for a cooling device in a cylindrical mr - the imaging system (100) hf - coil is used, said device:– a gradient coils winding (114) of hollow, cylindrical configuration,– a hollow cylindrical hf - coil (130), the concentric to and is slightly smaller than the gradient coils winding (114)– an outer cylinder (132), on the inner surface of the hf - coil (130) is mounted,– an inner cylinder (131), of the concentrically with respect to the outer cylinder (132), and– a number of spacer elements (133), which extends from the inner cylinder (131) extend radially outwards and on the outer cylinder (132) with the formation of coolant ducts (134) between the inner and the concentric outer cylinder (131, 132) are fastened.
