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.
