This study is aimed at investigating possibility of Impedance CT applying two-dimensional analysis. Two-dimensional Electrical Impedance CT has two advantages. This analysis method can estimate internal conductivity distribution faster and the number of required electrodes is fewer compared to three-dimensional analysis. It is suitable for using clinical application. At first, we tried to apply easy filter using the ratio of the potential distribution. However the result of the analysis had the image with noise and indicated not so correct conductivity distribution. The results depend on the relationship between conductivities and positions of the object of different conductivity and tissue around it. It was found that the problem caused by the difference of dimensions occurred. Therefore we need to apply new filter to eliminate the influence of the difference of dimensions. By using a new filter based on Neural Network, it was suggested that the correct conductivity distribution can be obtained.
