Figure 1
Imaging results for an in situ mouse lung: data acquired in 10 s, sample-to-detector distance 142 cm, E = 22 keV, pixel size = 25 µm. (a) Reconstructed raw data of a central slice through the lung (field of view ∼1 cm × 1 cm × 0.4 cm). A high noise level but also strong phase effects are visible. (b) The same slice reconstructed after single distance phase retrieval (delta-to-beta ratio of 1950). Lung septum, bigger air-filled spaces (bright), vessels and soft tissue (dark) are displayed. (c) The projected minimum over ten slices shows vessels (white arrowhead) and soft tissue. (d) The projected maximum over ten slices displays airways (black arrowhead). (e) Volume rendering representation, virtually cut to show airways (grey) and vessels and soft tissue (red). |
