Abstract
A reconstruction algorithm based on applying of a current pattern using electrodes is considered in the paper. A resulting voltage distribution between electrodes is measured. To improve an accuracy of the reconstructed image two FEM models are used -- a dense one in the forward problem and coarse one in inverse problem. A one-step version of the algorithm is examined and the results are compared with these obtained from iterative version of the algorithm. The reconstruction algorithm based on Levenberg-Marquardt approach is utilized. It has been found that the errors of images depend on object properties and can vary significantly in one-step version of reconstruction algorithm.
