Design optimisation of a Field Free Point Magnetic Particle Imaging scanner

Magnetic Particle Imaging (MPI) is a new imaging technology based on the non-linear magnetisation of magnetic nanoparticles which can be used as a tracer material. In a high speed 1D MPI Device, a sinusoidal signal containing a single frequency generate a time-varying magnetic field via the drive coil. We propose to use a COMSOL Multiphysics® simulation to be able to calculate otherwise hard-to-obtain values. With those quantities, we will be able to adapt the scanner design before the construction, by including the coupling between the coils and the effectiveness of the shielding in the design process. The simulation of the scanner allows us to optimise the system before construction, which was done before through many prototyping iterations.
