Abstract

A magnetic resonance unit includes a shim coil apparatus and a gradient coil apparatus. The shim coil apparatus is configured to compensate for basic magnetic field inhomogeneities of the first order in an examination region of the magnetic resonance unit. The shim coil apparatus includes at least one shim coil element. The gradient coil apparatus is arranged in a gradient coil layer. In addition to the gradient coil apparatus, at least one part of the at least one shim coil element is arranged in the gradient coil layer.
