Paper Abstract

In order to improve our ability to use electromagnetic fields to diagnose and treat disease, it would be helpful to know the electric conductivity in the interior of the body. In order to obtain this information, our group of Rensselaer has built devices, which we call Adaptive Current Tomograph (ACT) systems, that apply small currents to the body through electrodes stuck to the skin. The ACT systems measure the induced voltages, and send all the current and voltage information to the computer, which uses an algorithm to process the data and reconstruct approximate images of the conductivity and permittivity in the interior.
