Single-Sided MPI without Selection Fields: Proof-of-Concept Results

In a standard single-sided magnetic nanoparticles (MNPs) systems, all coils including the selection field coils are positioned on one side of the object to be imaged. In this work, we propose a single-sided MPI system that combines a single-sided magnetic particle spectrometer (MPS) setup and linear movement to resolve the magnetic nanoparticle (MNP) distribution along the axis of the system, without the need for selection fields.
