Magnetic Particle Imaging (MPI) is a new medical imaging method, first presented by Gleich and Weizencker in 2005. Since then, Different Scanner designs have been published. In 2009 Sattel et al. presented an innovative single-sided scanner topology. It has the advantage of an unlimitedpatient access. The MPI process in general, is based on the excitation of super-paramagnetic iron oxidenanoparticles by a sinusoidal varying magnetic field. Additionally, a selection field is generated, which induces a field-free point (FFP). The FFP enables spatial encoding, since only SPIONs in the FFP and its direct neighbourhood generate a significant magnetization dynamics, which is high enough to be recoreded. In this contribution, the measured system matrix of a second-generation oil colled single-sided scanner is presented, and a first technical validation of penetration depth is performed.
