Biofilm imaging in porous media by laboratory X-Ray tomography: Combining a non-destructive contrast agent with propagation-based phase-contrast imaging tools
X-ray tomography is a powerful tool giving access to the morphology of biofilms, in 3D porous media, at the mesoscale. Due to the high water content of biofilms, the attenuation coefficient of biofilms and water are very close, hindering the distinction between biofilms and water without the use of contrast agents. Until now, the use of contrast agents such as barium sulfate, silver-coated micr...
متن کاملImaging biofilm in porous media using X-ray computed microtomography.
In this study, a new technique for three-dimensional imaging of biofilm within porous media using X-ray computed microtomography is presented. Due to the similarity in X-ray absorption coefficients for the porous media (plastic), biofilm and aqueous phase, an X-ray contrast agent is required to image biofilm within the experimental matrix using X-ray computed tomography. The presented technique...
متن کاملComparison of phase contrast X-ray computed tomography methods for non-destructive testing of materials
Currently the basis for standard X-ray computed tomography (CT) is absorption. A volumetric map of a specimen in three dimensions is generated from a set of absorption radiographs. The contrast of details strongly depends on a difference in absorption coefficient between the detail and the environment. However, when the absorption difference is low, sufficient contrast for a good quality X-ray ...
متن کاملApplications of gold nanoparticles for medical imaging
Background & Aim: Molecular imaging enables us to non-invasively visualize tissue microstructures and lesion characterization, allowing accurate diagnosis of diseases at early stages. A successful molecular imaging requires a nontoxic contrast agent with high sensitivity. Nowadays, a wide range of nanoparticles have been developed as contrast agents for medical imaging modalities. Here, we revi...
متن کاملComputed tomography based attenuation correction in PET/CT: Principles, instrumentation, protocols, artifacts and future trends
The advent of dual-modality PET/CT imaging has revolutionized the practice of clinical oncology, cardiology and neurology by improving lesions localization and the possibility of accurate quantitative analysis. In addition, the use of CT images for CT-based attenuation correction (CTAC) allows to decrease the overall scanning time and to create a noise-free attenuat...
