Classical electrical impedance tomography (EIT) is an imaging modality in which the internal volume impedivity distribution is reconstructed based on the known injected currents and measured voltages on the surface of the object. However, in many medical as well as industrial cases a spongy or porous object is measured and it is characterized by the surface conductivity instead of the volume one. We show in this paper the possibility of such an approach and we demonstrate it on two-dimensional (2D) examples. Further extension in three-dimensional (3D) problems is straightforward.
