Analysis on MIT System Parameters Based on the Three-Dimension Electromagnetic Simulation

Magnetic induction tomography (MIT) is a new noninvasive and functional imaging technology, the magnetic field distribution in the imaging region can provide reference information for MIT system, and it is important for improving the performance of magnetic induction signal detecting and image reconstruction. In this paper, we designed a three-dimension MIT system model and computed the magnetic field of imaging region. According to the simulation model, the influence factors such as the dimension of exciting coil, the frequency of the exciting signal were analyzed, and the principle of choosing exciting parameters of MIT system was proposed.
