摘　　要：为了研究性能更好的 EIT图像重构算法 ,我们对基于敏感性定理的 EIT图像重构算法进行了计算机仿真研究 ,并与几种常用图像重构算法进行比较 ,提出对基于敏感性定理的It is the intent of this paper to develop better reconstruction algorithm for electrical impedance tomograthy (EIT). Simulation study of the reconstruction algorithm based on the sensitivity theorem is made and the reconstruction algorithm is compared with other normal algorithms. The results indicate that sensitivity method as a kind of static reconstruction algorithm has higher accuracy and speed of iteration , so it is worth researching for laboratory modality work.
