Theoretical Research on Constructing Gradient Field in Magnetic Particle Imaging System With Superconductor

Abstract

As a novel detecting technique, the research on superconducting magnetic particle imaging (MPI) is still a virgin land to break. Here, comparative research between copper and MgB ₂ -based MPI is conducted to explore the performance of superconducting MPI in generating and controlling the gradient magnetic field. According to the theoretical calculation and simulation analysis at the mouse-scale, the superconducting MPI can serve as a potential replacement for the conventions with significantly reduced volume and weight, which provides an improved magnetic gradient with finer scanning region and effectively controls the unintended noises with the same frequency as the target signals.
