Title: Electric mammograph

Abstract: The electric mammograph is an electrical impedance tomograph device for obtaining three-dimensional images of the conductivity distribution in biological tissues. A planar array of electrodes is put in contact with the tissues of interest. An AC source is connected to a single remotely attached electrode and to one of the planar array electrodes. Potential differences between the at rest electrodes in the planar array and a second remote at rest electrode are measured. The images are reconstructed using a modified back projection method.
