Electrical Capacitance Tomography System
Electrical Capacitance Tomography is a non intruding technique used in industries. It is based on measuring the capacitance of multi-electrode ECT sensor produced by the change in dielectricity or due to change in concentration of material. With the use of computed values, a cross sectional image of the material placed in the dielectric medium is obtained. ECT system can be used in chemical fie...
متن کاملMultiphase permittivity imaging using absolute value electrical capacitance tomography data and a level set algorithm.
Multiphase flow imaging is a very challenging and critical topic in industrial process tomography. In this article, simulation and experimental results of reconstructing the permittivity profile of multiphase material from data collected in electrical capacitance tomography (ECT) are presented. A multiphase narrowband level set algorithm is developed to reconstruct the interfaces between three-...
متن کاملImage Reconstruction of an Electrical Capacitance Tomography System Using an Artificial Neural Network
Abstract – In this paper, an image reconstruction algorithm for an electrical capacitance tomography (ECT) system is presented. It is based on an artificial neural network (ANN) Four kinds of grid in the same pipe and with different resolutions are discussed. The sensitivity of a pixel in each grid has been calculated and analyzed. The trained neural network has been applied to experimental dat...

This article reports recent advances and progress in the field of electrical capacitance volume tomography (ECVT). ECVT, developed from the two-dimensional electrical capacitance tomography (ECT), is a promising non-intrusive imaging technology that can provide real-time three-dimensional images of the sensing domain. Images are reconstructed from capacitance measurements acquired by electrodes...
متن کاملNovel Iterative Image Reconstruction Algorithm for Electrical Capacitance Tomography: Directional Algebraic Reconstruction Technique
Electrical capacitance tomography (ECT) is used to obtain information about the distribution of a mixture of dielectric materials inside a vessel or pipe. ECT has several advantages over other reconstruction algorithms and has found many applications in the industrial fields. However, there are some difficulties with image reconstruction in ECT: The relationship between the permittivity distrib...
