Codice 41/2017 Titolo Reconstruction of a piecewise constant conductivity on a polygonal partition via shape optimization in EIT Data 2017-07-26 Autore/i Beretta, E.; Micheletti, S.; Perotto, S.; Santacesaria, M. Link Download full text Abstract In this paper, we develop a shape optimization-based algorithm for the electrical impedance tomography (EIT) problem of determining a piecewise constant conductivity on a polygonal partition from boundary measurements. The key tool is to use a distributed shape derivative of a suitable cost functional with respect to movements of the partition. Numerical simulations showing the robustness and accuracy of the method are presented for simulated test cases in two dimensions.
