Comparison of the Forward Problem Computation of Magnetic Induction Tomography on Two Kinds of 3D Brain Numerical Model

Magnetic induction tomography (MIT) is aiming to reconstruct the cross-section conductivity distribution of subject using contactless method. The trends of possible data are vital to be understood. when some conductivity perturbation object is in a subject. In-this paper, a three-layer brain model and a three-layer concentric sphere model are made to calculate the phase shift data, which is necessary for simulating the measuring data of MIT with 16 coils. Comparing the data curves from two models, the shape of the model can change the symmetry and value difference of phase shift data although the main trends of the data are similar.
