Abstract
We introduce an output least-squares method for impedance tomography p roblems that have regions of high conductivity surrounded by regions o f lower conductivity. The high conductivity is modelled on network app roximation results from an asymptotic analysis and its recovery is bas ed on this model. The smoothly varying part of the conductivity is rec overed by a linearization process as is usual. We present the results of several numerical experiments that illustrate the performance of th e method.
