摘要： 快速有效的图像重建算法是电容层析成像技术(ECT)的关键。基于Landweber迭代法,导出一种快
速ECT图像重建迭代格式,分析了该迭代格式的收敛条件,并运用有限元仿真进行验证。结果表明,该迭代格式与
常用的Landweber算法相比,成像质量相同,但迭代速度快,受像素个数影响不大,有望应用于在线成像。

Abstract:  

Fast algorithm with high spatial resolution was the key to electrical capacitance tomography(ECT). A fast iterative scheme for electrical capacitance tomography was presented based on the Landweber iteration method. The convergence condition for the new method was also discussed. Simulated data were analyzed to evaluate the performance of the method. The results indicate that it can produce similar quality images with less reconstruction time when compared to the Landweber iteration algorithm. The reconstruction time does not depend heavily on the number of pixels. It shows good potential for online image reconstruction.
