Abstract

Magnetic particle imaging (MPI) is a novel functional imaging modality capable of detecting a distribution of superparamagnetic iron oxide (SPIO) tracer material in-vivo in 3D and real-time. Conventional MPI uses a sensitive spot method to scan the region of interest. To increase the sensitivity, however, an alternative encoding scheme using a line detection method was introduced. To provide the magnetic fields needed for dynamic line scanning in MPI a very efficient imager with respect to power consumption is needed. At the same time, the imager needs to provide a high magnetic field quality to ensure that no artifacts are introduced using efficient Radon-based reconstruction methods arising for a line encoding scheme. In this work, the most efficient dynamic FFL scanner design is presented, which outperforms all formerly introduced scanners with respect to magnetic field quality as well as electrical power consumption.
