Electrical impedance tomography — (EIT), is a medical imaging technique in which an image of the conductivity or permittivity of part of the body is inferred from surface electrical measurements. Typically conducting electrodes are attached to the skin of the subject and small… … Wikipedia
Electrical capacitance tomography — (ECT) is a method for determination of the dielectric permittivity distribution in the interior of an object from external capacitance measurements. It is a close relative of electrical impedance tomography [ M Soleimani, W R B Lionheart,… … Wikipedia
Electrical resistivity tomography — (ERT) or electrical resistivity imaging (ERI) is a geophysical technique for imaging sub surfaces structures from electrical measurements made at the surface, or by electrodes in one or more boreholes. It is closely related to the medical imaging … Wikipedia
tomography — [tə mäg′rə fē] n. 〚< Gr tomos, a piece cut off (see TOMY) + GRAPHY〛 a process for producing an image of a single plane of an object excluding all other planes, as by using CT SCAN or ULTRASOUND, in … Universalium
Electrical conductivity — or specific conductivity is a measure of a material s ability to conduct an electric current. When an electrical potential difference is placed across a conductor, its movable charges flow, giving rise to an electric current. The conductivity σ… … Wikipedia
