Position dependent response of Magnetic Nanoparticles using Magnetic Particle Imaging (MPI)

This paper presents the design and implementation of magnetic particle imaging (MPI) for 1D phantom imaging. Selection field setup, transmit and receive coil is designed and simulated in COMSOL Multiphysics
^®
. Comprehensive analysis of the selection field and homogenous transmit field superposition is carried out in COMSOL. 1D phantom is scanned at different positions inside the field of view (FOV). Optimum signals are achieved at static field free point (FFP) and minimum signals are observed at the boundaries (zero velocity of FFP) of the FOV.
