Simulation Study for Forward Problem in Magnetic Induction Tomography By COMSOL

Abstract

Simulation of forward problem for eddy current in magnetic induction tomography is one of the key issues in development of the technology of MIT. 2D and 3D MIT forward problem were built by finite-element model (FEM) based on the COSMOL software. Simulate to obtain magnetic flux density for 3D model with different eddy current distribution and make the results be compared, conclude regularity for change of 2D eddy current magnetic flux density influenced by excitation coils. These results provide crucial basis for forward problem and image reconstruction of MIT.
