Abstract
A convergence study of the forward problem of electrical impedance tomography is performed using triangular highorder piecewise polynomial finiteelement methods (pFEM) on a square domain. The computation of pFEM for the complete electrode model (CEM) is outlined and a novel analytic solution to the CEM on a square domain is presented. Errors as a function of meshrefinement and computational time, as well as convergence rates as a function of contact impedance, are computed numerically for different polynomial approximation orders. It is demonstrated that pFEM can generate more accurate forward solutions in less computational time, which implies more accurate simulated interior potentials, electrode voltages and conductivity Jacobians.
