Paper Abstract

Magnetic Particle Imaging (MPI) has been presented by Gleich and Weizenecker in 2005. Since then, a number of innovations have been introduced by many di erent research groups. In 2009, for instance, Sattel et al. presented a novel single-sided MPI scanner geometry. The major advantage of this particular scanner geometry is the unlimited measurement eld. For the imaging process in MPI, super-paramagnetic iron oxide nanoparticles (SPIONs) are applied as tracer material. The tracer is excited by sinusoidally varying magnetic elds. In this contribution, simulated magnetic elds were evaluated based on the measured eld distribution of a single-sided scanner realization. It is of particular importance to know the quality of the gradient elds, since image resolution in MPI is directly linked to the gradient strength.
