基于SR-CT技术对残缺投影数据进行了研究。通过数值模拟分析了影响残缺投影数据重建结果的主要因素:重建算法和投影间隔角。获得了重建算法和投影间隔角与残缺投影数据重建结果之间的关系。实验结果证实了分析的正确性。
The incomplete projection data is researched based on synchrotron radiation computed-tomography technology. The two major factors impacted the reconstrueted results of incomplete projection data: reconstructed methods and the projection interval angle are analyzed by digital simulation method. The relations are given between them and reconstrueted results. The experimental results confirm this analysis.
