ABSTRACT
Human tissue is electrically conductive, with tissue conductivity varying signicantly between dierent tissues. Electrical impedance tomography (EIT) is a relatively new imaging modality, rst developed in Sheeld, UK in 1982 (Brown and Barber), whose purpose is to produce images from the internal conductivity distribution of an object, based on measurements collected from the surface of the object (Kohn and Vogelius, 1984a,b; Sylvester and Uhlmann, 1986). e original assumptions made were of the near-isotropic distribution of conductivity of the imaged object.
