Abstract: A control system and data acquisition system for an electrical capacitance tomography sensor comprised of a sensor having a plurality of electrodes, where each electrode is further comprised of a plurality of capacitance segments. Each of the capacitance segments of each electrode can be individually addressed to focus the electric field intensity or sensitivity to desired regions of the electrodes and the sensor.

Abstract: Dynamic three-dimensional image electrical capacitance tomography sensor system is disclosed. The technique generates, from the measured capacitance, a whole volume image of the region enclosed by the a geometrically three-dimensional capacitance sensor. A real time, three-dimensional imaging of a moving object or a real time volume imaging (i.e., four-dimensional (4D)) allows for a total interrogation scheme of the whole volume within the domain of an arbitrary shape of geometry to be implemented. The system comprises a 3D capacitance sensor, data acquisition electronics and the image reconstruction algorithm which enables the volume-image reconstruction. The electrode shape of the capacitance sensor can be rectangular, triangular, trapezium, or any shape to enclose a 3D section of the measuring domain and to distribute the electrical field intensity in three directions with equal sensitivity strength.
