Abstract介绍了X射线荧光层析成像技术的成像原理及其在微量分析领域中的应用。针对X射线与物质相互作用时,不仅产生荧光,而且会产生各种散射光,为消除这些散射光对成像结果的影响,提出采用在与人射X射线垂直方向放置一个圆环状的晶体单色器,即双聚焦模式晶体单色器,使荧光与各种散射光分离,并聚焦在探测器上。这样不仅大大增强了荧光信号的强度,而且可使荧光探测器小型化。

Other AbstractThe imaging principle of X-ray fluorescent tomography and its application in microanalysis field are introduced simply. Not only fluorescence but also various scattered light are produced while high energy X rays interact with substance. In order to eliminate the influence of these scattered light to imaging result, a method is proposed in which a doubly focusing crystal monochromator is placed normal to the accident X rays to separate X-ray fluorescence from the background and focuse it to a point on the detector surface. The method not only enhances the intensity of X-ray fluorescence but also permits the use of a smaller detector.
