摘要
同步辐射微束X射线荧光CT(SR-XFMT)是一种能无损、高空间分辨和高灵敏地探测样品内部元素含量和分布的新技术．对SR-XFMT实验进行了计算机模拟,讨论了采样间隔和投影数对重构质量的影响,分析发现采样间隔对重构质量的影响比投影数的影响要大．
Synchrotron Radiation based X-ray Fluorescent Microtomography （SR-XFMT） is a nondestructive technique for detecting elemental composition and distribution inside a specimen with high spatial resolution and sensitivity. In this paper, computer simulation of SR-XFMT experiment is performed. The influence of the sampling interval and the number of projections on the quality of SR-XFMT image reconstruction is analyzed. It is found that the sampling interval has greater effect on the quality of reconstruction than the number of projections.
