Abstract

Magnetic particle imaging (MPI) is a tracer based tomographic imaging technique that uses static and oscillating magnetic fields to generate an image contrast from the spatial distribution of magnetic nanoparticles. Recent investigations have shown that the MPI is able to generate additional contrasts from different tracer materials or their environments. For example, multi-contrast MPI can be used to determine the viscosity or temperature of the particle environment, or to distinguish tracer particles based on their core size. In this work, we investigate a novel contrast based on the magnetic anisotropy of immobilized particles which allows to estimate the orientation of samples.
