I. Introduction
In the electrical impedance tomography (EIT), the voltage or current is injected into the object with a set of electrodes attached to its surface [1, 23–26]. The voltage values are measured on the remaining electrodes. The conductivity of the object is reconstructed based on the measurements made and an appropriate algorithm to solve the inverse problem [15, 16, 18, 19, 21, 22, 30–32].
