Figure 2
FBP CT reconstructions of the imaginary part, β, of the X-ray complex refractive index using the full sets of 28920 projections [7232 projections for two configurations, (45 keV, 5 m) and (50 keV, 5 m)], for 12 combinations of the sample-to-detector distance and X-ray energy. Left to right: 0.27 m, 1 m, 2 m, 5 m; top to bottom: 38 keV, 45 keV, 50 keV. The calibration bars in the left-most plots show β × 1011.
