Abstract: In this paper, we present a new Finite Volume Method (FVM) which is based on the current continuity theory. We employed this new method for solving Electrical Impedance Tomography (EIT) forward problem. Then compared it to the analytic solution of models of 2D homogenous circle and 3D homogenous spheres. Accurate potential distribution can be obtained even with the coarse meshes using this method. Combining FVM for EIT forward problem with sensitivity matrix method for reconstructing the conductivity changes, relative higher resolution results was obtained in the reconstruction imaging of conductivity changes. The averaged amplitude of the perturbation can reach up to 80% which is much higher than the previous report of 30%.
