Method and magnetic resonance system for homogenizing the B1 field |
摘要 |
In a method and magnetic resonance system for homogenization of the B<SUB>1 </SUB>field for a magnetic resonance data acquisition with a number of iteration steps. An iteration step includes the following sub-steps: Measurement data are acquired that represent a B<SUB>1 </SUB>field distribution in at least one part of the examination volume of the magnetic resonance system. A B<SUB>1 </SUB>homogeneity analysis based on the acquired measurement data is automatically implemented. A specific homogenization action is automatically selected from among a number of possible homogenization actions based on the B<SUB>1 </SUB>homogeneity analysis, or the iterative homogenization method is ended if the diagnosed homogeneity is sufficient for an intended magnetic resonance measurement. The selected homogenization action is implemented.
