From: High resolution propagation-based lung imaging at clinically relevant X-ray dose levels
Comparison of the different imaging setups based on scans of three different healthy pig lungs. (a) High resolution clinical CT, effective pixel size \(455\,\upmu \hbox {m}\), entrance dose 13 mGy. (b) SyRMeP synchrotron setup, SDD 2.7 m, effective pixel size \(89\,\upmu \hbox {m}\), entrance dose 10 mGy. (c) SyRMeP synchrotron setup, SDD 10.7 m, effective pixel size \(67\,\upmu \hbox {m}\), entrance dose 10 mGy. (d), (e), (f) show zoomed in parts of the images above. Clearly, the Synchrotron data sets surpass the image quality of the clinical HRCT scan. Moreover, the data acquired at lower dose at 10.7 m are of better image quality than the one scanned at shorter sample-to-detector distance.
