Biofilm imaging in porous media by laboratory X-Ray tomography: Combining a non-destructive contrast agent with propagation-based phase-contrast imaging tools
Fig 6
Profiles of the volumetric fractions (S: solid, L: liquid, BF: biofilm) obtained for the different datasets (BaSO4: small dashes, FeSO4: longer dashes).
The shaded region is defined by the results obtained for the threshold sensitivity analysis. For the sake of clarity, the results of this sensitivity analysis are not added to the liquid phases. The average volumetric fractions (in percent) for the different phases (Solid VS, Liquid VL, Biofilm VBF) obtained with the two different contrast-enhancing agents is given in the legend.
