  • 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 ...
  • 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 ...
  • Greenwood, Charlene; Rogers, Keith; Wilson, M.; Lyburn, Iain Douglas; Evans, P.; Prokopiou, Danae (IOP, 2019-03-18)
    Osteoporosis is a prevalent bone disease around the world, characterised by low bone mineral density and increased fracture risk. Currently, the gold standard for identifying osteoporosis and increased fracture risk is ...
  • Dicken, Anthony; Spence, Daniel; Rogers, Keith; Prokopiou, Danae; Evans, Paul (Royal Society of Chemistry, 2018-09-13)
    To retrieve crystallographic information from extended sample volumes requires a high-energy probe. The use of X-rays to combine imaging with materials characterisation is well-established. However, if fundamental ...
  • Prokopiou, Danae; McGovern, James; Davies, Gareth; Godber, Simon; Evans, Paul; Dicken, Anthony; Rogers, Keith (International Union of Crystallography, 2020-07-24)
    A new approach to parafocusing X-ray diffraction implemented with an annular incident beam is demonstrated for the first time. The method exploits an elliptical specimen path on a flat sample to produce relatively high ...
  • Prokopiou, Danae; Smith, Kerrie L.; Rogers, Keith; Paula, P.; Evans, Paul; Dicken, Anthony; Godber, S. (International Union of Crystallography, 2017-04-01)
    Diffraction data may be measured using approaches that lead to ambiguity in the interpretation of scattering distributions. Thus, the encoding and decoding of coherent scatter distributions have been considered with a ...
