“…Another word, an element of the Jacobian matrix in the derivative of the measured capacitance at the boundary divided to the derivative of permittivity of a voxel [7]. An efficient formulation to calculate the Jacobian matrix uses the results of the forward problems and mutual energy concept to calculate the Jacobian matrix [4,15]. The solution of the forward problem and the Jacobian matrix is used to solve the inverse problem, which is the estimation of the permittivity distribution given the measured capacitance data.…”

“…There has been a great deal of progress in image reconstruction methods, especially applied to 2D ECT; however, 3D ECT presents especially challenging numerical issues [8,15,17,18,20,21]. 3D ECT is valuable for imaging the volumetric distribution of electrical permittivity.…”

“…3D ECT image reconstruction presents a similar inverse problem to electrical impedance tomography (EIT) which has been extensively studied, so ECT will naturally benefit from progress in EIT image reconstruction. Similar to EIT, Microwave tomography [17], ECT has potential to generate images with high temporal resolution and relatively poor spatial resolution. The spatial resolution is limited as a result of the inherent ill-posedness of the inverse problem and the existence of modeling and measurement errors and limited number of independent measurements.…”

Abstract-Electrical capacitance tomography (ECT) is a relatively mature non-invasive imaging technique that attempts to map dielectric permittivity of materials. ECT has become a promising monitoring technique in industrial process tomography especially in fast flow visualization. One of the most challenging tasks in further development of ECT for real applications are the computational aspects of the ECT imaging. Recently, 3D ECT has gained interest because of its potential to generate volumetric images. Computational time of image reconstruction in 3D ECT makes it more difficult for real time applications. In this paper, we present a robust and computationally efficient 4D image reconstruction algorithm applied to real ECT data. The method takes advantage of temporal correlation between 3D ECT frames to reconstruct movies 4D of dielectric maps. Image reconstruction results are presented for the proposed algorithms for experimental ECT data of a rapidly moving object.Corresponding author: M.

“…Many researchers have proposed real three dimensional conductivity imaging [Davidson 2004;Sun 2012] and permittivity imaging [Soleimani 2006;Wajman 2006;Fan 2007;Banasiak 2010;Yan 2013] reconstruction methods, to achieve a better understanding of industrial processes. Sometimes with a fast sampling speed system, 2.5D images can also be achieved, by stacking several 2D images together [Ye 2012].…”

SUMMARYWe have investigated the estimation of the location of a dielectric from the capacitance measured with widely spaced measurement electrodes provided with a shield and additional electrodes. In order to investigate the estimation method, a numerical technique was developed for calculating the capacitance between widely spaced measurement electrodes by finite element analysis. We discuss the new method for estimation of the locations of two dielectrics by using a capacitor with widely spaced parallel electrodes and additional electrodes.
