Abstract

Magnetic particle imaging (MPI) is a noninvasive imaging method that detects superparamagnetic iron oxide (SPIO) nanoparticles within the body by their nonlinear behavior in the presence of external magnetic selection field. This study characterized a small-scale MPI magnet. The researchers have been able to shift the Field Free Line (FFL)through the field of view by altering the currents in the two coils as predicted in the simulations. Preliminary measurements indicate that the iron-returned FFL magnet is a promising design approach for future projection and Magnetic Computed Tomography MPI scanners.
