【摘要】 本文提出了正交有限视角少数投影光学层析技术重建图像的重要性；对正交光路系统各１６°，１４°，１２°，１０°范围内的投影视角采用联合代数重建算法实现了图像重建的计算机模拟；分析了重建精度与采样密度、采样间隔的关系。结果表明，小视角少数投影情况下重建出较高质量的图像是可行的。更多还原

【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.更多还原
