Abstract:
1. A method for setting a shim to homogenize a magnetic field of a magnetic resonance apparatus, said magnetic field being generated in the magnetic resonance apparatus to assist in acquiring magnetic resonance exposures of a predetermined examination region, comprising the steps of: in a computer, at least semi-automatically designating a three-dimensional volume that is relevant for setting a shim for acquiring magnetic resonance data from an examination region using an examination protocol, said computer at least automatically setting said three-dimensional volume matched to at least one of said examination region and said examination protocol by selecting said three-dimensional volume from a plurality of arbitrary morphology sets of selectable volumes, not limited to specific volume shapes, or by generating said three-dimensional volume as an arbitrary three-dimensional volume not limited to a specific volume shape; and in said computer, automatically calculating said shim for said three-dimensional volume that has been at least semi-automatically designated, and making the calculated shim available as an output from the computer in a form for implementing said shim in said magnetic resonance apparatus.
