    Osteoporotic fractures present a significant social and economic burden, which is set to rise commensurately with the aging population. Greater understanding of the physicochemical differences between osteoporotic and ...
  • Confocal energy-dispersive X-ray diffraction tomography employing a conical shell beam 
    Dicken, Anthony; Evans, J. Paul O.; Rogers, Keith; Prokopiou, Danae; Godber, Simon; Elarnaut, F.; Shevchuk, Alex; Downes, D.; Wilson, M. (Optical Society of America, 2019-07-01)
    We introduce a new high-energy X-ray diffraction tomography technique for volumetric materials characterization. In this method, a conical shell beam is raster scanned through the samples. A central aperture optically ...
  • Conical shell illumination incorporating a moving aperture for depth-resolved high-energy X-ray diffraction 
    Spence, Daniel; Dicken, Anthony; Downes, David; Rogers, Keith; Evans, Paul (Royal Society of Chemistry, 2023-01-16)
    In many applications, the main limitation of X-ray absorption methods is that the signals measured are a function of the attenuation coefficient, which tells us almost nothing about the chemical or crystallographic nature ...
  • Contrasting the crystallinity indicators of heated and diagenetically altered bone mineral 
    Rogers, Keith; Beckett, Sophie; Kuhn, Samira; Chamberlain, Andrew; Clement, John (Elsevier, 2010-10-01)
    Modifications to bone mineral as a result of diagenesis or heating include a marked increase in crystallinity. Although these processes are not completely understood a number of simple, pragmatic approaches are in general ...
  • Depth resolved snapshot energy-dispersive X-ray diffraction using a conical shell beam 
    Dicken, A. J.; Evans, J. Paul O.; Rogers, Keith; Prokopiou, Danae; Godber, S. X.; Wilson, M. (Optical Society of America, 2017-08-23)
    We demonstrate a novel imaging architecture to collect range encoded diffraction patterns from overlapping samples in a single conical shell projection. The patterns were measured in the dark area encompassed by the beam ...
