Seminar

Calderon's inverse problem in 2D Electrical Impedance Tomography

Astala, K (University of Helsinki)

Seminar Room 1, Newton Institute

Abstract

Calderon's problem asks if and how one can determine the conductivity structure of a material from boundary current-voltage measurements. In two dimensions the problem admits a complete solution. This includes the uniqueness proof for (very) rough coefficients, developing new reconstruction algorithms and their computer implementation.

In this talk we give an overview of the recent progress on the EIT problem in two dimensions. The talk is based on joint works with M. Lassas, L. Päivärinta, S. Siltanen, J. Müller and A. Perämäki.
