Abstract

Magnetic Particle Imaging (MPI) uses sinusoidal drive fields to excite the magnetic nanoparticles. These time-varying magnetic fields form electric fields within the body, which in turn can cause peripheral nerve stimulation, also known as magnetostimulation. In this work, we propose a design for a human head-size magnetostimulation coil with a Rutherford cable winding. This design achieves 12-fold decrease in the voltages needed to generate a given magnetic field, facilitating the safety of human subject experiments. With electromagnetic simulations, we determine the electric field patterns on a human head model to determine the potential primary locations of magnetostimulation.
