| Abstract: | Electrical impedance tomography is a new technology of medical imaging, which can be used to detect the real time internal electrical impedance. This article is doing research on the method of electrical impedance tomography by conjugate gradient iterative algorithm. The finite element analysis software COMSOL is utilized to make a two-dimensional model about a circular field with 16 electrodes. The software MATLAB is used to finish the tomography reconstruction work by applying two different reconstruction algorithms. After tomography reconstruction, a variety of evaluation methods and numerical analysis is applied to estimate the reconstructed image quality, such as the correlation coefficient and the similarity relative error evaluation. |
