Abstract

We propose a nonlinear multigrid approach for imaging the electrical conductivity of a body, given simultaneous measurements of d.c. electric currents and voltages at the boundary. The implementation is done for an output least squares formulation of the electrical impedance tomography problem. Extensions to a stronger, variational approach are discussed, as well.
