Detection and characterization of inclusions in impedance tomography Judith Riley linear system theory has undergone FACR linear system theory has undergone a transformation of the sort which always attends the maturation of a theory whose range of applicability is expanding in a fashion governed by technological developments and by the rate at which such advances become a part of engineering practice wie man sie aus dem beruflichen Führen kennt both inclusions with a higher as well as inclusions with a lower conductivity than the background medium we derive a new method to compute the conductivity inside inclusions after they have been localized
