A system and method for Displacement Current Phase Tomography. The present system invention obtains a linear relationship between mutual displacement current from a sensor (output current of the measuring electrode terminals) and the area (or volume) of an object to be imaged in the imaging domain. The system uses capacitance sensors and utilizes the phase of the measured current, in addition to the amplitude, to reconstruct an image.

Displacement current phase tomography for imaging of lossy medium

The present invention provides a system and method for velocity vector field calculation at the voxel level of a multi-phase flow system using Electrical Capacitance Volume Tomography sensors.

Velocity vector field mapping using electrical capacitance sensors

A method and system for generating a three-dimensional tomograph of a vessel interior or other object using a sensor having a plurality of electrodes and active control segments that are electrically isolated from the electrodes.

Active control guards and rationometric calibration and reconstruction for use with electrical capacitance volume tomography

A capacitance system having a capacitance sensor provides a high resolution Spatial-Adaptive Reconstruction Technique (SART) for use with Adaptive Electrical Capacitance Volume Tomography (AECVT). The system is adapted to analyze information provided by an image reconstruction of a first spatial region of an imaging domain of the sensor; provide control signals to the sensor to increase the resolution at a second spatial region of the imaging domain of the sensor based on the prior image reconstruction of the first spatial region; obtain image reconstruction information for the second spatial region of the imaging domain; and combine the image reconstruction information for the first spatial region and the second spatial region to obtain a combined image of the imaging domain.
