Mr gradient coil system with a shim tray receptacle at a position unaltered by temperature changes

摘要

A gradient coil system has at least one shim receptacle space for passive shim elements and a decoupling device with which a volume change of components of the gradient coil system caused by a temperature change is mechanically decoupled from the shim receptacle space. The decoupling device is arranged in the gradient coil system so that the shim receptacle space remains unvaried in position relative to a defined point of a volume to be shimmed.
