Electrical capacitance tomography

Patent Granted 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[1] and is proposed as a method for industrial process monitoring, although it has yet to see widespread use. Potential applications include the measurement of flow of fluids in pipes [2] and measurement of the concentration of one fluid in another, or the distribution of a solid in a fluid.
