Originální abstrakt

In electrical impedance tomography (EIT) currents are applied through the electrodes attached on the surface of the object, and the resulting voltages are measured using the same or additional electrodes. Internal conductivity distribution is recalculated from the measured voltages and currents. The problem is very ill posed, and therefore, regularization has to be used. The aim is to reconstruct, as accurately as possible, the conductivity distribution in two and three dimension model using finite element method (FEM). In this paper are proposed new variations of the regularization for an accurate reconstruction. The proposed method is expected to be used for the non-destructive testing the materials for presence of the different kinds of breaches or cracks.
