| Abstract(in English) | Impedance computed tomography is greatly limited by a ill-conditioning matrix. It results in large reconstruction errors or sometimes failure to obtain any image. A fixed coefficient method can modify the updating equation and to solve the divergence problem greatly. However, determination of a good coefficient depends the mass experiments and the one's experience. In this paper, an automatic method with successive determination of variables is introduced. Besides, we have evaluated the performance of the fixed coefficient method and the successively variable method with two phantoms. As a result, it was found that the successively variable method is efficient and is more practical in use. |
