Magnetic Particle Imaging (MPI) is a new imaging method, which was first presented by Gleich and Weizenecker in 2005. Since then, there have been many innovations in MPI, such as the single-sided scanner design, introduced by Sattel et al. in 2009. Its major advantage lies in the optimised use regarding patient access. This contribution is concerned with the simulation of the single-sided design in Comsol Multiphysics®(Comsol), a commercial simulation software for physical processes. This promotes the research into MPI, since the various capabilities of Comsol enables a more comprehensive simulation of the single-sided MPI scanner design.
