Region-of-Interest Phase Contrast CT of Calf Lungs with varying exposure times

Region-of-interest propagation-based phase contrast images acquired at the Imaging and Medical Beamline (IMBL) of the Australian Synchrotron. The dataset comprises an inflated calf lung taken at a propagation distance of 5 m using monochromatic X-rays at 70 keV. Saccharose was injected to emulate the image signal of tumor tissue.
