Abstract
Multi-color Magnetic Particle Imaging (MPI) offers the ability to distinguish magnetic nanoparticles (MNPs) based on their physical states, enhancing its use in functional imaging and interventional guidance. This study explores the limits of solid-liquid phase differentiation in multi-color MPI. A customized MPI setup was used to test mixed-phase samples, highlighting the relationship between the solid-liquid phase differentiation resolution and system detection resolution. Results show that improving solid-liquid phase differentiation requires both point spread function (PSF) optimization and increased system detection resolution.
