| 摘 要： | 本文尝试将一种新型的基于Landweber迭代算法用于电阻抗断层图像(EIT)重建。该算法与线性反投影算法不同，Landweber算法可以明显地改进图像质量。仿真结果表明，它不仅可以消除噪声干扰，而且能加快收敛速度。

| Abstract: | This paper attempts a novel iteration algorithm to be used in Electrical Impedance Tomography based on the modified Landweber iteration method. Unlike the linear back projection method, the Landweber algorithm can greatly improve the quality of the image. The simulating results show that it can not only provide a better immunity to noise but also improve the convergence speed. |
