摘要
作为具有国际先进水平的第三代同步辐射光源,上海光源的X射线亮度比普通X光管高12~16个量级,基于它的X射线成像具有高空间分辨、高衬度分辨和快时间分辨的特点,同步辐射X射线可对样品实现原位、无损、高分辨、三维和动态成像,而且可以实现相位衬度成像,从而将X射线成像的应用领域拓展到软组织、聚合物等低Z材料。自2009年正式向用户开放以来,上海光源已在生物医学、材料科学、古生物学、土壤学等领域取得了一大批重要研究成果。为更好地支持用户,上海光源X射线成像组在定量成像、CT成像、快速CT重构等成像方法学领域开展了较为全面、系统的研究,大幅提高了实验效率和对不同样品的适应性。本文简要介绍了上海光源X射线成像方法学发展及相关应用研究进展。
Abstract
The X-ray flux of Shanghai synchrotron radiation facility (SSRF), a world-class SR source of the third generation, is about 12 to 16 orders of magnitude higher than X-ray tube flux. SR imaging has properties of high spatial resolution, high contrast resolution and high time resolution. The SR imaging can obtain in-situ, non-destruction, high-resolution, three-dimension and dynamic imaging of samples; moreover, the phase imaging technique can be utilized which can extend its applications to low-Z materials like soft tissue and polymer. Since SSRF was formally opened to users in 2009, it has made significant research results in the fields of biomedical, materials science, paleontology, pedology and so on. In order to further support users′ experiments, the SSRF X-ray imaging group has carried out systematic X-ray imaging methodology researches in quantitative imaging, tomography, fast tomography data processing and so on, which substantially increases the experimental efficiency and sample adaptability. The progress of X-ray imaging methodology and its applications at SSRF are introduced.
