Abstract

The steering of microrobots by using magnetic fields offers applications for minimally invasive surgery or forestablishing drug delivery scenarios. On the one hand, magnetic particle imaging (MPI) offers a tomographic, realtime visualization of the used magnetic microrobots. On the other hand, an MPI scanner can apply magnetic fields, which a microrobot can be steered with. Hence, MPI is of great interest for realizing the tracking and navigation of microrobots. Here, we show that a microrobot, which has been coated with superparamagnetic iron oxide nanoparticles (SPIONs) can be steered through a patient specific phantom of the middle cerebral artery into an aneurysm, where it should occlude the aneurysm and can be potentially used for a triggered drug release or a hyperthermia treatment. The acquired MPI images show that a tracking accuracy of 0.68mmis achieved.
