System function analysis of MPI with Field-Free Line and excitation coil configurations

Year: 2024

Type: article

Abstract: Magnetic Particle Imaging (MPI) visualizes the distribution of magnetic particles using their nonlinear magnetization response. This study evaluated the impact of interference between the Field-Free Line (FFL) and alternating excitation field on system performance. The Coaxial Configuration suppressed interference and provided stable in-phase signals, while the Orthogonal Configuration produced anti-phase signals, reducing sensitivity. The Coaxial Configuration is suitable for wide-area measurements, whereas the Orthogonal Configuration offers high resolution but faces sensitivity challenges.
