Fig. 3 . PR processing using PITRE software. The 16-bit raw projections were corrected to remove their background noise. For PR-based PCI, PR processing was performed to get the PR-based floating-point images. For PR-based PCCT, PR processing was performed to get PR-based projections before the gaining of the sinograms. The floating-point sinograms were then reconstructed into floating-point slices. Finally, the floating-point images or slices were converted to 8-bit. PCCT, phase-contrast CT; PCI, phase-contrast imaging; PITRE, Phase-sensitive X-ray Image processing and Tomography REconstruction; PR, phase retrieval.
