The purpose of electrical impedance tomography (EIT) is reconstruct an image of the electric conductivity distribution in transversal section of body by measuring voltages induced on the electrodes attached to the body surface while currents are passed between them. On this measurement data of currents and voltages the image of conductivity distribution inside bioobject is reconstructed [1, 2].References
