Abstract：Construction and simulation of finite element models of human body were needed to analyze the influences of physiological and pathological factors and evaluate the qualities of reconstruction algorithm in EIT (Electrical Impedance Tomography). As a commonly-used model at present, traditional 2D (Two Dimensional) models were incapable to perform some of the 3D (Three Dimensional) simulation and researches. In view of this problem, the paper proposed a method for construction and simulation of a 3D brain finite element model for EIT. The model was built firstly through application of COMSOL. Then, a simulation experiment was performed with the application of combination of MATLAB and COMSOL. According to the results, the method could rapidly realize the construction and simulation of complicated models which would be further used for researched on brain imaging.
