Description

Electrical impedance tomography (EIT) is a non-destructive monitoring technique. The inverse problem of EIT shows serious nonlinear and ill-posed nature, which leads to the low spatial resolution of the reconstructed images. The iterative idea is an effective method to deal with the inverse problem for imaging, the existing iterative imaging methods, however, have many drawbacks, such as needing huge computational resources and unstable convergence properties. To solve the above-mentioned problems, this paper proposes an improved Landweber iterative image reconstruction framework. By carefully designing a regularization term in the optimization function of the iterative framework, this method improves the convergence speed. The tank experiment results show that the improved Landweber method is superior to the traditional Landweber method in convergence speed.
