Figure 1
The in vivo imaging set-up in the BL20XU imaging hutch with the approximate path of the X-ray beam shown in yellow. A diagram of the set-up was shown previously by Parsons et al. (2008). The X-ray beam passed through a shutter, ion chamber and the mouse trachea before reaching the X-ray converter and camera. The propagation distance between the mouse and X-ray converter was 135 cm. The hand of a researcher is visible on the right, preparing to deliver a particulate sample to the mouse trachea. |
