Abstract

We consider the problem of determining conductivity anomalies inside a body from voltage-current measurements on its surface. By combining the monotonicity method of Tamburrino and Rubinacci with the concept of localized potentials, we derive a new imaging method that is capable of reconstructing the exact (outer) shape of the anomalies. We furthermore show that the method can be implemented without solving any non-homogeneous forward problems and show a first numerical result.
