Application of synchrotron X-ray microtomography in paleontology for nondestructive 3-D imaging of fossil specimens

摘要: X射线无损成像技术在古生物化石标本研究领域中应用十分广泛.近几年来，随着技术的不断革新，同步辐射X射线相衬显微断层成像技术(SRX-PC-μCT)也被引入到这一领域.由于同步辐射光源产生的硬X射线具有高亮度、高准直性和高空间相干性等优点，可以实现化石标本高分辨率（亚微米级）的无损三维显微成像，给古生物学的发展带来了新的机遇.文章简要回顾了用于古生物化石标本无损成像技术的发展历程，并在此基础上综述了同步辐射X射线断层显微成像技术在古生物学领域的应用现状和前景.

Abstract: X-ray imaging has been employed in paleontology for more than 100 years, and has made great contributions to the nondestructive studies of paleontological fossil specimens. With the development of X-ray technology, a new type of nondestructive imaging, synchrotron X-ray microtomography, has been applied to this field in recent years. This is a special kind of micro-computer tomography based on hard X-rays from synchrotron radiation, which is characterized by high brilliance, high transverse spatial coherence and a high degree of uni-directionality. Nondestructive 3-D imaging with submicron resolution of fossils is now possible, opening up new possibilities for paleontology. This paper reviews recent developments and future prospects of the application of phase-contrast-enhanced synchrotron X-ray microtomography in paleontology.-
