Abstract: 
Grating-based X-ray dark-field (XDF) imaging is highly promising for diagnostic lung imaging. Previous small-animal studies have revealed a decrease in XDF signal for various structural lung pathologies, which typically are characterized by changes in alveolar structure.
By additionally exploiting the energy-dependency in grating-based XDF imaging with use of spectral detection, more information about the microstructure of the observed object can be accessed. Here we present a correlation between the structure size of complex samples closely resembling human lung tissue and grating-based spectral XDF imaging with a polychromatic X-ray source, which is of peculiar interest for future diagnostic XDF imaging.
