| Zusammenfassung | Magnetic particle imaging (MPI) is a tomographic imaging method to determine the spatial distribution of magnetic nanoparticles (MNP) within a defined volume. To evaluate the spatio-temporal resolution of existing MPI scanners, enabling a comparison of the performance of different setups, we developed dynamic MPI measurement phantoms. These segmented flow phantoms consist of a bolus of ferrofluid tracer material, pumped through a tube system. Using a hydrophobic organic carrier oil, cylindrically shaped bolus of different diameter, length,MNPconcentrations, and flowvelocity can be emulated. Moving boluseswere imaged byMPI and the correlation of spatial resolution und velocity of the bolus was investigated. For all bolus dimension and flow velocity combinations, for increasing bolus velocity and decreasing bolus volume a decreasing spatial resolution and increasing blurring with was observed.
