Current density distributions on electrodes

The understanding of the current density distribution on electrodes used in Electrical Impedance Tomography (ΕIΤ) is important in the application of image reconstruction algorithms. It is particularly important in iterative schemes where the forward problem of calculating the electric potential from boundary Dirichlet and Neumann data is solved many times. In this paper we present the results of some analytic calculations which have been made as a contribution to the understanding of this problem.
