Figure 13
Raw projection image (left, scaled between 70 and 240) and tomographic slices without (centre, scaled between −0.0022 and 0.003) and with Paganin phase retrieval (right, scaled between −1 × 10−6 and 6 × 10−6) of a fuel cell sample (Marone et al., 2020). Fast scan, 611 projection images of 2016 × 300 pixels (∼733.2 MB), consisting of 10 dark images (∼12 MB), 100 initial flat-field images (∼120 MB), 401 data images (∼481.2 MB), and 100 terminal flat-field images. The pixel size is 2.75 µm and the scale bar corresponds to 800 µm. (Data courtesy of Jens Eller, Paul Scherrer Institut.) |
