Abstract

The image reconstruction for electrical capacitance tomography (ECT) is a nonlinear, underdetermined and ill-posed inverse problem. It is difficult to achieve a reconstructed image with higher quality, especially in 3D reconstruction. The study of image reconstruction algorithm is a crucial issue in ECT. In this paper, a novel algorithm of image reconstruction (MLRALI) applying to 3D ECT is presented. The basic idea behind this algorithm is to establish the forward problem by utilizing multiple-linear regression without utilizing sensitivity matrix, then achieve a stable solution of the inverse problem by utilizing an accelerated Landweber iteration algorithm. Extensive simulations have demonstrated that the algorithm proposed has better reconstruction performance compared with the Landweber iteration algorithm utilizing sensitivity matrix for direct 3D reconstruction.
