TB Portals - Case 422

These models are NOT intended for 3D Printing. They models have full-color materials when viewed in "3D Mode"

The following models were generated for TB in 3D in NIAID's TB Portals as part of World TB Day 2022. This case can be displayed in the TB in 3D viewer by selecting case 304 from the TB in 3D Gallery .

This case has 4 timepoints included. Details about the case can be found in the TB Portals Case Browser .

Manual segmentations were done in 3D Slicer using thresholding tools and brushes. 3D surfaces were exported from 3D Slicer then processed in Pixologic ZBrush. This processing included smoothing of lung surfaces, removal of artifacts and undesired features, and reduction polygon number for optimal browser rendering.

light blue = infiltrate

yellow = foci

black = cavities

red = foci + infiltrate + fibrosis (indistinguishable)

AI segmentations (where available) were done using an AI based segmentation service developed by the Biomedical Image Analysis Group, United Institute of Informatics Problems, National Academy of Sciences of Belarus. 3D surfaces were created in 3D Slicer, then the resulting meshes were decimated to reduce the polygon number while minimally affecting surface boundaries.

black = cavities

red = foci

tiel = fibrosis

Note: structures inside the lung lobes have been UVd and include AO maps.
