Abstract :
To improve the speed and quality of the reconstruction image for Electrical Capacitance Tomography (ECT), a fast image reconstruction algorithm based on Engle criterion is proposed. ECT image reconstruction is an ill-posed problem, and Tikhonov regularization is employed to get the stable solution. Engle criterion is used to choice regularization parameter. A further research about three-order method for fast choosing regularization parameter is proposed. Simulation results show that the proposed method has fast convergence rate and the reconstruction image quality is improved markedly.
