Simulation of a modular coil unit for a preclinical MPI scanner

The adoption of preclinical Magnetic Particle Imaging (MPI) as a standard technique in research heavily relies on the availability of scanners with a low entry barrier. One of the barriers is the infrastructure demand of such a system in terms of space, electric supply power and cooling. Scanners that try to tackle this require power-efficient transmit coil assemblies. Here, the design process of such a set of coils is presented and the optimization steps are discussed. With a total power loss of 1.2 kW for the drive and focus fields and a field of view (FoV) of 33.8 mm at 5 T m-1 the whole system can potentially be powered from a single power outlet.
