Raw projection image (left, scaled between 250 and 850) and tomographic slices without (centre, scaled between −0.0007 and 0.0012) and with Paganin phase retrieval (right, scaled between 1 × 10−6 and 7 × 10−6) of a drying porous catalyst structure (Marone et al., 2020). Fast scan, 1251 projection images of 2016 × 1400 pixels (∼6.75 GB), consisting of 50 dark images (∼270 MB), 100 initial flat-field images (∼540 MB), 1001 data images (∼5.4 GB), and 100 terminal flat-field images. The pixel size is 0.85 µm and the scale bar corresponds to 225 µm. (Data courtesy of Vladimir Novak, Paul Scherrer Institut.) |
