Figure 4
The two-dimensional data set is azimuthally integrated to produce one-dimensional patterns. The data representation S(y, [omega]) required for the reconstruction is the global sinogram. All sinograms have been represented before direct beam intensity normalization. Different regions of interest (ROIs), corresponding to phases differentiated through their d spacing, are selected: in this example (a) capillary, (b) crystalline diamond, (c) amorphous carbon and (d) graphite-like carbon. The reconstruction provides the intensity distribution as a two-dimensional image (x, y) for each ROI [a detailed analysis for this sample is given by Álvarez-Murga et al. (2012BB3)].  [article HTML]
