Abstract :
In this paper the two conductivity distribution reconstruction algorithms are presented. The first based on the previous resistivity reconstruction and the second one based on the usage of the inverse measured voltages. Efficiency of the presented algorithms compared with the direct conductivity distribution. Modeling results shows that these two algorithms provide better convergence of the iteration process of solving the inverse tomography problem.
