Description

Electric Current Computed Tomography (ECCT) is a technique for producing images of the electrical resistivity profile within a body from measurements made on the body’s exterior. To make these measurements, an array of electrodes is attached to the surface of the body. Sets of current patterns are applied through these electrodes and the voltages needed to maintain these specified currents are measured and recorded. These applied currents and measured voltages are then used in a reconstruction algorithm to produce images that represent approximations to the electrical resistivity distribution in the interior of the body.
