Abstract:
A gradient coil system comprising a plurality of gradient coil system components including a gradient coil, at least some of said gradient coil system components being subject to a change in volume due to a temperature change, all of said gradient coil system components being combined in a unitary assembly defining a shim receptacle space, enclosed within said unitary assembly of said gradient coil system components, wherein said shim receptacle space is adapted to receive a shim element magnetically shimming a shimming volume, and a decoupling device embodied in said unitary assembly and interposed between said at least some of said gradient coil system components in said unitary assembly and said shim receptacle space, said decoupling device mechanically decoupling said shim receptacle space from said volume change of said at least some of said gradient coil system components, said decoupling device being disposed in said unitary assembly relative to said at least some of said gradient coil system components and said decoupling device maintaining said shim receptacle space in an unaltered position relative to a defined point in said shimming volume despite said change in volume.
