ABSTRACT:
A magnetic resonance apparatus is provided with a detection system comprising a coil, which may be part of a shim coil system. Signals detected by this system are used for a dynamic control of a shim coil system in order to mitigate dynamically adverse influences of eddy currents on the magnetic field homogenity in at least a region of interest within the coil system of the apparatus.
