Magnetic Particle Imaging is a promising imaging technique using iron-oxide nanoparticle tracers. The spatial distribution of these particles can be determined by solving a system of linear equations. This reconstruction is based on a system function that either has to be measured or can be calculated with given information about scanner topology and particle characteristics. This paper introduces a new approach combining both possibilities. A Magnetic Particle Spectrometer is used to obtain a hybrid system function. Furthermore, we will show that the hybrid system function can be successfully used for 1D-image reconstruction and potentially is an alternative to the measurement-based system function.
