T142 0-40 Sentence denotes Tissue compactness and distance metrics:
T143 41-153 Sentence denotes The 3D reconstructions of the lung tissue were analyzed in terms of specific surface and characteristic lengths.
T144 154-214 Sentence denotes The workflow is sketched for sample V in the top part (a–g).
T145 215-271 Sentence denotes In a first step, the tissue was segmented using Ilastik.
T146 272-334 Sentence denotes A slice of the reconstructed electron density is shown in (a).
T147 335-571 Sentence denotes Based on the segmentation, the areas of air which are directly connected and potentially filled with oxygen (or blood) are masked out (b). (c) For each of the remaining tissue voxels the shortest possible distance to air was calculated.
T148 572-682 Sentence denotes Especially around vessels and larger alveoli, the distances are larger. (d) Zoom into an area around a vessel.
T149 683-1001 Sentence denotes Further analysis is based on the distance distribution shown in (e). (f) Volume rendering of the reconstructed electron density, with (g) showing the corresponding 3D distance map. (h) Based on the tissue segmentation of all samples, the distance from the tissue interior to the closest air compartment was calculated.
T150 1002-1115 Sentence denotes In order to compare all samples, the count of voxels was normalized by the total volume of the respective sample.
T151 1116-1299 Sentence denotes The specific surface area SV (represented by the first value of each curve), the characteristic length Lc and the mean distance dO2¯ for each sample was calculated based on this data.
T152 1300-1369 Sentence denotes Double logarithmic scale, bin width of the distribution of distances:
T153 1370-1376 Sentence denotes 1 v⁢x.
T154 1377-1403 Sentence denotes Scale bars: (a–c) 100⁢μ⁢m.
