Simulation Analysis on Stimulation Modes of Three-Dimension Electrical Impedance Tomography

To improve the lack of information and model error of twodimensional electrical impedance tomography (EIT), a three-dimensional EIT model is set up. Finite element method is used to calculate the forward problem. To compare different stimulation mode, distinguish ability and surface projection method are used. The result shows that back electrode mode has obvious advantages in detecting depth and in clinical use. The conclusion of this paper can provide reference for the study of three-dimensional EIT.
