Abstract

A magnetic resonance apparatus has a gradient coil system having at least one gradient coil for generating a magnetic gradient field and an electrically conductive structure that is arranged and fashioned such that the gradient field is damped in a region outside the imaging volume of the magnetic resonance apparatus, and such that a magnetic field of the structure caused by the gradient field via induction effects is similar in structure to the gradient field, at least within the imaging volume.
