Main Article Content
Magnetic Particle Imaging (MPI) is a promising imaging modality for medical applications, which exploits the non-linear magnetization curve of magnetic nanoparticles to visualize the spatial distribution of the tracers. In addition to this diagnostic application, MPI can also be used for therapeutic purposes, like magnetic hyperthermia or targeted drug delivery. Both applications require the knowledge of the temperature of the MNPs and their environment. One opportunity to determine the temperature of MNPs is to detect the phase lag of the particles due to the temperature change. With our single-harmonic-based narrowband MPI system we can measure images of the MNP concentration via the harmonic amplitudes and images of the temperature exploiting the phase of a harmonic. As a next step we work on a combination of both modalities to enable a simultaneous and quantitative concentration and temperature imaging.
