Abstract

A local gradient coil arrangement having an essentially hollow-cylindrical geometry can be separated at at least one side along a separating line proceeding in the axial direction of the arrangement. All gradient coil conductors that would cross the separating line are interrupted at the separating line. The currents at each side of the separating line are carried via connecting lines that proceed parallel to the separating line. The gradient coil arrangement can thus be divided into two parts without having to provide contacts between these two parts.
