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

Abstract

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 that is based on a field-free point (FFP) 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 design of a single-sided MPI device that has an advantage of a more sensitive field-free line (FFL) topology.
