Abstract
Electrical Impedance Tomography (EIT) is a technique which attempts to create images of the electrical conductivity distribution of the material in the interior of an object. In many situations the widely differing electrical properties of the various types of matter within the object mean that the image so created is effectively an image of the distribution of these different type of material. The method proceeds by applying a variety of electric currents to the object using electrodes placed on its surface. A voltage distribution is induced in the object and this is measured on its surface, again via a number of electrodes. These data are used by a reconstruction algorithm to generate the image of the internal conductivity distribution.
