To this end, magnetic particles are injected into the blood stream.A strong external magnetic field with a field-free point (FFP) is applied, suchthat the magnetic moments of the particles align with this field, with theexception of the FFP. A second external field, the so-called excitation field,is applied to change the magnetization of the particles that are situated inthe FFP. This change in the magnetization induces an electric current in thereceive coils, which yields the data for this imaging technique. In orderto obtain an image of the entire body, the FFP is moved along a trajectorythat covers the area of interest. Both the calibration as well as the imagingprocess itself require the solution of inverse problems. This talk is intendedto give an overview of MPI and the arising mathematical challenges.Vortragende(r)Anne WaldKontaktSenka Haznadar (senka.haznadar@aau.at)
