Abstract

This paper presents a method to design and simulate excitation coil (drive coil) for single-sided magnetic particle imaging (MPI) scanner. Magnetic excitation of the magnetic nanoparticles (MNPs) used as the tracer is paramount so that their non-linear magnetization response will be acquired for image reconstruction. Numerical simulation of the magnetic field produced by the excitation coil in the form of solenoid is carried out in Matlab using Biot-Savart law. The results are compared with that of Ansys Maxwell software simulation and experimental results of the excitation coil having the same specifications. The solenoid simulated has 350 turns of copper wire (0.6mm diameter) and 2A excitation current, produces a magnetic field of around 1.49 mT using Matlab, 1.51 mT using Ansys Maxwell and 1.82 mT experimentally, at the surface of the coil. These magnetic fields values are within the excitation range for MPI, hence sufficient for the MNPs excitation from singlesided scanner topology.
