Figure 5. Phase contrast images of a 1-week-old male mouse imaged at 33 keV. (a) Propagation-based imaging (PBI) with l2=4.26 m. Image size: 54.07 mm x 16.79 mm. Black region of interest (ROI): 200 x 200 pixels. White ROI: 70 x 70 pixels. Exposure time: 5.0 s. Surface entrance dose: 8.6±0.3 mGy. (b) Analyser-based imaging (ABI) image of the same mouse. Image size: 64.26 mm x 11.29 mm. Black ROI: 200 x 200 pixels. White ROI: 50 x 50 pixels. Exposure time: 0.5 s. Surface entrance dose: 0.95±0.03 mGy.
