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 contact conductance between the electrode and the object is a source of deformation field and it has to be taken into account in image reconstruction. As the physical dimensions of the volume conductivity and the contact conductivity are different, it is difficult to include both quantities in different regularization terms. In the paper we propose a simple modification model of contact conductivity so that it can be used in the total variation regularization term.
