X-ray fluorescence imaging

Over the past two decades, numerous X-ray micro„beam studies have been published addressing the nondestructive investigation of chemical element distribution in condensed heterogeneous media. Based on this literature, some aspects of the field are discussed in this paper, including X-ray focusing methods and various elemental imaging techniques: scanning and confocal X-ray fluorescence microscopy, full-field X-ray fluorescence microscopy, X-ray fluorescence tomography, and prospects for combining X-ray fluorescence imaging with other physical methods rested on using synchrotron radiation.
