Abstract

Model-based reconstruction is still one of the key challenges in magnetic particle imaging (MPI) when using multi-dimensional Lissajous-type excitation. Besides an appropriate particle model, the model of the MPI system for signal generation and reception has a major impact on the modeled system matrix. We outline the influence of the latter MPI scanner parameters on the system matrix pattern and review methods to calibrate each parameter.
