Raw projection image (left, scaled between 400 and 1800) and tomographic slices without (centre, scaled between −0.0025 and 0.0035) and with Paganin phase retrieval (right, scaled between −2 × 10−5 and 5 × 10−5) of an evolving magma (Marone et al., 2020). Fast scan, 751 projection images of 1008 × 1900 pixels (∼2.85 GB), consisting of 50 dark images (∼190 MB), 100 initial flat-field images (∼380 MB), 501 data images (∼1.9 GB), and 100 terminal flat-field images. The pixel size is 2.75 µm and the scale bar corresponds to 365 µm. (Data courtesy of Mattia Pistone, University of Georgia.) |
