A novel image reconstruction algorithm accelerated based on polynomials for electrical capacitance tomography system

摘要

To solve the problem of two-phase flow measurement for electrode electrical capacitance tomography (ECT), on the basis of analyzing ECT system measurement principle, we constructed the mathematical model of two-phase flow distribution information according to double integral infinitesimal principle, and formed a set of 12-Electrode two-phase ECT system. And to speed up the slow convergence rate of ordinary iteration method, a novel regularization image reconstruction algorithm Accelerated based on the Polynomials of for electrical capacitance tomography is presented. Experimental results and simulation data indicate that the algorithm can provide high quality images with less reconstruction time and few iteration steps and this new algorithm presents a feasible and effective way to research of image reconstruction algorithm for Electrical Capacitance Tomography System.
