Abstract

A gradient coil system for a diagnostic magnetic resonance apparatus has two gradient coil arrangements rotated perpendicular to one another, for the production of transverse magnetic field gradients. The two gradient coil arrangements each have several coil pairs arranged along an axis. The coil pairs are each formed by two gradient coils of the segment type. The respective numbers of coil pairs in the two gradient coil arrangements are different from one another, and the gradient coils of the two gradient coil arrangements mutually overlap one another.
