Figure 9
Powder diffraction images of a mixture of chalcedony and iron oxide pigments without (a) and with (b) saturated pixels as a result of a large quartz crystallite being present in the beam trajectory. (c) Sinogram S(y, [omega]) and (e) reconstructed image as obtained from (b) without correction; (d) sinogram and (f) reconstructed image obtained after correction using a dynamic threshold mask during integration.  [article HTML]
