The disclosure relates to a method for operating a magnetic resonance apparatus, to a magnetic resonance apparatus, and to a computer program product. According to the method, a pre-measurement is carried out by the magnetic resonance apparatus, wherein carrying out the pre-measurement includes acquiring pre-measurement data for the object under examination. The pre-measurement data is evaluated to ascertain evaluation information. The evaluation information is used to determine whether a B1 field map needs to be measured.

Method for operating a magnetic resonance apparatus, magnetic resonance apparatus and computer program product

A method for determining a Bmap for, for example, performing an imaging magnetic resonance measurement using a magnetic resonance apparatus, includes measuring an original magnetic field distribution in a measurement volume of the magnetic resonance apparatus, and computing a final Bmap that describes a magnetic field distribution produced in the measurement volume of the magnetic resonance apparatus by setting a shim state. The magnetic field distribution produced in the measurement volume of the magnetic resonance apparatus by setting the shim state differs from the original magnetic field distribution.
