Method and magnetic resonance system for homogenizing the B1 field

A magnetic resonance system for homogenizing a B1 field, for magnetic resonance data acquisition in the magnetic resonance system, in at least one region of an examination volume in the magnetic resonance system, comprising:

• a measurement device for acquiring measurement data representing a B1 field distribution in said region of said examination volume;
• a computer;
• a control unit for operating said measurement device and said computer in an iterative procedure comprising a plurality of iterative steps including acquiring said measurement data and, in said computer, based on said measurement data, automatically analyzing a homogeneity of said B1 field, and dependent on the analysis of said homogeneity, automatically selecting a homogenization action from among a plurality of available homogenization actions, or ending said iteration procedure if said homogeneity is sufficient for acquiring said magnetic resonance data;
• and
• if a homogenization action has been selected, said computer instructing said control unit for implementing the selected homogenization action.

A computer program product loadable into a computer of a magnetic resonance system for homogenizing a B1 field, for magnetic resonance data acquisition in the magnetic resonance system, in at least one region of an examination volume in the magnetic resonance system, said computer program product causing said computer to execute a plurality of iteration steps, and in each iteration step:

• causing a measuring device of said magnetic resonance system to acquire measurement data representing a B1 field distribution in said region of said examination volume;
• causing said computer, based on said measurement data, to automatically analyze a homogeneity of said B1 field;
• causing said computer, dependent on the analysis of said homogeneity, to automatically select a homogenization action from among a plurality of available homogenization actions, or to end said iteration procedure if said homogeneity is sufficient for acquiring said magnetic resonance data;
• and
• if a homogenization action has been selected, causing said computer to instruct a control unit of the magnetic resonance system to implement the selected homogenization action.
