X‑ray dark‑field imaging is sensitive to unresolved microstructure and has strong potential for lung tissue characterization, disease identification, and virtual histology. However, quantitative dark-field CT remains challenging due to uncertainties in the vi...

X-ray grating interferometry enables the simultaneous acquisition of attenuation, dark-field, and differential phase-contrast images. Dark-field provides sensitivity to sub-resolution microstructural variations inaccessible to conventional radiography. This c...
