Navigation of the micro-robot with an MPI scanner through the aneurysm phantom. The path through the aneurysm phantom is approximated by four straight path segments by using the CAD model. According to the path segments the focus fields are calculated, such that the field vector rotates in the plane perpendicular to the path segment. A rotation frequency of 5 Hz and an amplitude of 3 mT is applied. The video stills show the resulting movement of the micro-robot through the human phantom, which was filled with a red stained glycerol-water mixture to mimic the viscosity of blood. The measurement is conducted inside an MPI scanner. The video can be found in the Supplementary Material.
