Zusammenfassung: | In electrical impedance tomography, an inverse problem has to be solved to reconstruct the complex conductivity distribution /spl kappa/=/spl sigma/+j/spl omega//spl epsiv/. The problem is ill posed, and therefore, a regularization has to be used. The aim is to reconstruct, as accurately as possible, both the electric conductivity /spl sigma/ and the electric permittivity /spl epsiv/ in three dimensions using finite elements of the second order for solving the forward problem. To this end, a new reconstruction algorithm based on a priori information has been developed. |
