Magnetic Particle Imaging (MPI) is a novel tomographic imaging method. Sattel et al. first described a single-sided MPI scanner geometry. Here, sentinel lymph node biopsy for breast cancer as a medical application scenario for single-sided MPI is presented. Furthermore, simulations of different coil geometries for 2D imaging have been performed. Fi-nally, the transfer functions of three implemented band-pass filters have been measured, confirming high spectral purity of the excitation signals.
