Abstract

The authors present results obtained by iterative application of the 'backprojection along equipotentials' algorithm for electrical impedance imaging (EII). The forward problem of EII is solved using the finite-element method FEM. Results are presented for the selection of a mesh for FEM, trading accuracy with computation power available. A 1016-triangular-element mesh is found to be optimum. An algorithm is also developed to scale the nodes of the mesh to divide any geometry defined by the positions of the electrodes. Images obtained using data from circular and noncircular 2-D phantoms of known conductivity distributions are presented. It is concluded that for quantitative imaging, iterative application of the method is essential.
