| Abstract: | A new algorithm of the image reconstruction on limited view CT using continuous HNN was presented. Two kinds of criteria were changed into the energy function in HNN to find the best solution. The numerical simulation was used to study the effect of image reconstruction and stability against noise. The results show that this algorithm has good accuracy. |
