Abstract
This paper describes electrical impedance tomography (EIT) sensitivity evaluation using two models. The first is the classical circular twodimensional (2D) model used by past authors. The second is a threedimensional (3D) cylindrical model, which takes into account the height of the object under study. Having reported the analytical expression of the potential Field of the 2D model, we derive an equivalent solution for the 3D case. Having analyzed the convergence of the solutions, we compute for different conductivity perturbations the ratio of the sensitivities obtained with the two models. Results indicate that the 2D model, as compared with the 3D model, generally overestimates sensitivity by a factor of two unless the conductivity perturbation is extensive and more conductive than the principal medium. In such a case, the 2D model tends to underestimate EIT sensitivity.
