| Abstract: | A novel image reconstruction algorithm for Electrical Capacitance Tomography(ECT) is presented.According to the ill posed characteristics of ECT inverse problem the minimum norm solution was improved on the basis of analyzing the algorithm,and the stabilization of the numerical solution was proved via singular value decomposition principle.In addition,a new objective functional was established;in the process of solving the functional regularization technique was vised to ensure the stabilization of numerica... |
