Abstract
In a method for operating a magnetic resonance apparatus with a gradient coil system and an active shim system, shim currents of the active shim system and/or offset currents of the gradient coil system are adjusted corresponding to at least one subject-specific parameter of an examination subject.
Claims15
A method for operating a magnetic resonance apparatus having a gradient coil system and an active shim system and an imaging volume adapted to receive a portion of an examination subject, said method comprising the steps of:
- without conducting a magnetic resonance examination of said examination subject, identifying at least one subject-specific parameter of said examination subject;
- and
- adjusting at least one current, selected from the group consisting of shim currents of said active shim system and offset currents of said gradient coil system, dependent on said at least one subject-specific parameter for obtaining a selected homogeneity within said imaging volume for a subsequent magnetic resonance examination using said magnetic resonance apparatus with said portion of said examination subject received in said imaging volume.
