Biofilm Imaging in Porous Media by Laboratory X-ray Tomography: Combining a Non-Destructive Contrast Agent with Propagation-Based Phase-Contrast Imaging Tools.
Segmented FeSO4 Raw FeSO4 control data after Lorentzian filter application Origin Data
Segmented control data presented in Carrel et al. (2017). Here no growth medium was added, but the same concentration of contrast agent was recirculated in the column as a control. A Lorentzian filter applied on the radiographs allowed to substantially enhance contrast and reduce noise.
