Single-Sided Field-Free Line Generator Magnet for Multi-Dimensional Magnetic Particle Imaging

Magnetic particle imaging (MPI) is an emerging medical imaging modality that is not yet adopted by clinical practice. Most of the working MPI prototypes, including commercial-grade research MPI scanners, utilize cylindrical bores that limit the access to the scanner and the imaging volume. Recently, a single-sided or an asymmetric device, which is based on a field-free point coplanar coil topology, has been introduced that shows promise in alleviating access constraint issues. In this paper, we present a simulation study of selection coils for a novel theoretical approach of designing a single-sided MPI device that has an advantage of a more sensitive field-free line topology.
