| Abstract: | 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. |
