Abstract: Magnetic induction tomography is considered to be valuable in medical application of testing brain edema. In this paper, we use the edge finite element method with electric field intensity E as the vector variable to simulate a multi-channel measuring system based on a real human brain finite element model. In simulation, we change the conductivity of brain edema and the frequency of exciting current to research the performance of the multi-channel measuring system in testing the brain edema.

Keywords: Magnetic induction tomography, edge finite element method, simulation
