Figure 18
Cropped absorption (left) and phase contrast (right) reconstructed slices through a tomographic dataset of a fuel cell sample (Marone et al., 2020). From top to bottom the total scan time increased from 0.1 to 4 s. The SNR (calculated using the areas encompassed by the red rectangles) for the full tomographic volumes is indicated by the numbers in the slice corners. The grey-level values for the shown absorption and phase contrast reconstructions are scaled between −0.002 and 0.005, and −3 × 10−6 and 1.5 × 10−5, respectively. The scale bar corresponds to 400 µm.
