一种新算法在ECT图像重建中的应用研究
A Novel Algorithm of the Application in the ECT Image Reconstruction
摘要
Abstract
To solve the larger residual,small residual or zero residual problem and ihe slow convergence speed problem in ordinary iter-ation method, introducing NL2SOL optimization algorithm integrate the GaussNewton method, onv polynomial acceleration regularization it-erative capacitance tomography algorithm is proposed. On the basic of introducing the ultimate principle of 12-electrode electrical capacitance tomography system, the mathematical model of this algorithm is presented, and the convergence of this algorithm is proved by using the spectrum analysis. The proposed algorithm satisfy convergence conditions and small reconstruction error and having feasibility in the electri-cal capacitance tomography application is demonstrated through experiments.关键词
