Contrast-to-noise ratios and thickness-normalized, ventilation-dependent signal levels in dark-field and conventional <i>in vivo</i> thorax radiographs of two pigs
Published 2019“…Upon correlating this data, we discovered approximately linear relationships between the logarithmic dark-field signal and both projected quantities for all scans. Increasing ventilation pressure strongly decreased dark-field extinction coefficients, whereas the ratio of lung dark-field and attenuation signal changed only slightly. …”
