Development of MPI relaxometer for characterization of superparamagnetic nanoparticles
Journal of Magnetism and Magnetic Materials, 2021 Abstract This paper presents the design, implementation, and experimental measurements of a custom-made MPI relaxometer to characterize superparamagnetic iron oxide nanoparticles (SPIONs) as a tracer for Magnetic Particle Imaging (MPI). The relaxometer is electromagnetic interference (EMI) shielded and serves as a zero magnetic field MPI scanner at 4.
