摘　　要：利用新型第三代高亮度同步辐射光源相衬成像技术,可实现弱吸收(主要含碳、氢、氧和氮等元素)物质材料特征结构的无损三维鉴定。以具有极高药用价值的新疆地产药材——阿魏(Ferula)为研究对象,采用同步辐射高分辨X射线相衬显微CT技术,并结合相位恢复算法,有效解析和评价了新疆阿魏(F.sinkiangensis)的三维特征结构,极大提高了对药材类生物样品的显微结构和密度的分辨能力,从而为新疆阿魏的特征分辨、品质鉴定和真伪识别提供了一种直观可靠的三维可视化新手段。Synchrotron-based X-ray phase-contrast micro-tomography is being used for achieving nondestructive and 3-D characterization due to the high contrast imaging of low Z materials（consisting of C, H, O, N elements）. In this paper, we present a new method to combine the high resolution synchrotron-based X-ray phase-contrast imaging technology and phase retrieval algorithm for analyzing and evaluating the 3D inner micro-structures and nondestructive characteristic structures of Ferula sinkiangensis. The method successfully revealed the 3-D micro-structures and characteristics of F. sinkiangensis with high-density resolution, demonstrating that the method is an intuitive and reliable tool of 3D visualization, which has good potential for characterizing and identifying Chinese medicine materials.
