Correction of B0 field fluctuations in the breast at 7 tesla by fitting a dipole field to field probe data A simulation study

Respiration causes motion of boundaries with large susceptibilities differences, such as the shoulders, the heart and the diaphragm. These motions can cause artefacts in a variety of MR scans. With field probes the field fluctuations caused by this motion can be observed. However, these probes measure the field outside the body. In this simulation study we suggest to fit a dipole to field probe measurements to translate field fluctuations from outside the body to field fluctuations inside the breast.
