Figure 15
Raw projection image (left, scaled between 400 and 1100) and tomographic slice (right, scaled between −2 × 10−7 and 4 × 10−7) of an ice cream sample (Marone et al., 2020). Standard high-quality scan followed by Paganin phase retrieval, 2231 projection images of 2560 × 2160 pixels (∼24.7 GB), consisting of 30 dark images (∼331.8 MB), 200 initial flat-field images (∼2.2 GB), 1801 data images (∼19.9 GB), and 200 terminal flat-field images. The pixel size is 0.65 µm and the scale bar corresponds to 300 µm. (Data courtesy of Annabelle Medebach, Paul Scherrer Institut.) |
