Electrical capacitance volume tomography (ECVT) has shown to be an effective low-cost and high-speed imaging technique suitable for many applications, including 3-D reconstruction of multiphase flow systems. In this paper, we introduce the concept of adaptive ECVT based upon the combination of a large number of small individual sensor segments to comprise synthetic capacitance plates of different (and possibly noncontiguous) shapes while still satisfying a minimum plate area criterion set by a given SNR. The response from different segments is combined electronically in a reconfigurable fashion. The proposed adaptive concept paves the way for ECVT to be applicable in scenarios requiring higher resolution and dynamic imaging reconstruction. © 2001-2012 IEEE.


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.


A flexible capacitance sensor having multiple layers for communicating signals to a data acquisition system for reconstructing an image of an area or object located in a subject being sensed, the flexible capacitance sensor having a flexible layer of capacitance plates; a flexible shielding ground layer next to the layer of capacitance plates; a flexible layer of signal traces next to the shielding ground layer, where the layer of signal traces has a plurality of trace lines; and where the capacitance sensor is flexible and adapted to be wrapped around the subject being sensed. The sensor is adapted to communicate signals via the plurality of trace lines to a data acquisition system for providing an image of the area or object between the capacitance plates.
