| Abstract: | A new approximation method to distribution function of conductivity for electrical impedance tomography image reconstruction algorithm is proposed in this paper. This method is called continuous interpolation function method. Compared with the conventional piecewise constant method, the image reconstructed by this method is much better, while the amount of computation is not increased or even decreased because the good property of finite element method has been used sufficently. |
