In this paper the meshfree method is developed to solve the forward problem for electrical impedance tomography. Differing from finite element method and finite volume method, there is no mesh generation in meshfree method, which is easier to realize and more propitious to be developed as an adaptive procedures for image reconstruction. Numerical simulation results are presented and compared with the results of analytical solution. It is observed that the obtained results are consistent with the results of analytical solution.

W artykule zaproponowano nowa metodę tomograficznej analizy impedancji w której nie generuje się oczek jak na przykład w metodzie elementów skończonych. Dzięki temu uzyskuje się łatwiejsza analizę, w tym także metodami adaptacyjnymi.
