Panels (A)–(C) show the interesting areas in lung and airway imaging in an ex-vivo mouse model. (A) The nasal airways. The yellow box highlights the area which is imaged in Fig. 5 with the high resolution setup. (B) Trachea region (for A and B detector pixel size = 6.5 μm, exposure time = 1 s), (C) Lung (detector pixel size = 13 μm, exposure time = 1 s), (D) is a magnification of the red box in (C) and shows the speckle pattern which results from the air sacs in the lungs, the alveoli. (E) Overview scan of the ex-vivo mouse imaged with propagation-based X-ray phase-contrast, composite image using 1 m propagation and 10 second exposure times (detector pixel size = 6.5 μm). The green letters A, B, C indicates the regions where the images shown in panels A–C were taken. The mouse was fixed with a rubber band. In the stomach gas bubbles are visible (highlighted with blue arrows).
