摘要

Magnetic Particle Imaging (MPI) has been introduced as a modality that allows for the acquisition of three-dimensional functional images with high sensitivity in real time. Here, alternative coil topologies are presented that differ significantly from the original set-up. Two novel coil topologies will be presented. Beside an asymmetric coil topology, where all field generating coils are arranged on a single side, an effective coil assembly has been accomplished that creates a field-free line for spatial coding. The alternative coil topologies may overcome the problem of a confined measurement field or lead to an increase of the sensitivity of MPI.
