Single-Sided Hybrid Selection Coils for Field-Free Line Magnetic Particle Imaging

Abstract

Single-sided Magnetic Particle Imaging (MPI) is a promising new development that can help translating MPI technology into clinical practice. Unlike currently available closed geometry MPI scanners single-sided device does not have a hardware around the object thus providing unlimited access to the field of view from one of the sides. The major progress includes a demonstration of 2D imaging on a single-sided device that utilizes a field-free point coplanar coil topology. Previously, we proposed a design of a field-free line selection field generator for a single-sided geometry. Here, we extend our single-sided design to incorporate a much more efficient scheme that utilizes permanent magnets.
