Abstract

Actively shielded, transversal gradient coil system for a nuclear magnetic resonance tomography apparatus, wherein the windings of the coils implemented in 3D technology include a plurality of open conductor ends, and wherein the connector elements for conductor ends discharging between the center planes of neighboring shim pockets are planar plate connectors arranged in a plurality of planes, insulated from one another, that respectively include a base part secured to a carrier ring and lying completely outside the shim pocket and include conductor fastening legs projecting substantially radially outward therefrom that are arranged circumferentially offset relative to one another in the planes lying above one another.
