| Abstract: | In this paper, the importance of image reconstruction using Optical CTfrom a few projections in orthographic limited view angle is presented. Computersimulation of image reconstruction was realized using SART. The relationship among reconstruction precision, sampling density and sampling angle interval was analyzed.The resurt shows image reconstruction of high quality from a few prjections in small view angle is practical. |
