“…The maxima of the coherent cross sections occur at larger angles, thereby increasing the angular resolution. Grant et al (1993Grant et al ( , 1994Grant et al ( , 1995 have developed a microversion of a diffraction CT apparatus (figure 14). They do not use a ring-shaped detector and thus lose in efficiency.…”

“…In subsequent work by the same group (Grant et al 1994), they used synchrotron radiation tuned to give essentially monoenergetic radiation in the range 5 to 20 keV and showed that it is possible to map the spatial orientation of crystallites within specimens.…”

“…Harding and co-workers first demonstrated that crystallography and medical imaging techniques could be successfully joined to form a powerful new technique, mapping spatial variations in molecular structure throughout an extended, inhomogeneous specimen. 1,2 Several authors have followed suit [3][4][5][6][7][8][9][10][11][12][13] and proposed various methods for coherent-scatter imaging. Many applications have been proposed for public safety purposes, such as the screening of foodstuffs for contaminants or of checked baggage for explosives or drugs.…”

“…Harding et al adapted the ''white beam'' x-ray diffraction method to imaging, 3 using 100 kVp polychromatic radiation and an energy-resolving detector ͑high-purity germanium͒ at a fixed angle and performing a raster scan of the specimen. Other groups 8,15 have abandoned diagnostic sources and are developing tomographic systems using high brilliance, monochromatic synchrotron sources. These are not, however, widely accessible.…”

“…The original approach to image reconstruction in XDT (Harding et al 1985) utilized summation filtered backprojection (FBP). The limitations of FBP reconstruction in this context have been discussed by Grant et al (1993Grant et al ( , 1994. Despite its shortcomings for XDT, summation FBP continues to be the favoured approach for tomographic image reconstruction based on scattered x-ray data.…”
