Description

These models are NOT intended for 3D Printing. The GLB inputs have full-color materials which are visible when the NIH 3D viewer is in "3D" mode. The following models were generated for TB in 3D (https://tbportals.niaid.nih.gov/3d-gallery) in NIAID's TB Portals (https://tbportals.niaid.nih.gov/) 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 (https://tbportals.niaid.nih.gov/3d-gallery). This case has 3 timepoints included. Manual segmentations were done in 3D Slicer (https://www.slicer.org/) 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) cream = pleuritis AI segmentations (where available) were done using an AI based segmentation service (https://lungs.org.by/login/) 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 cream = pleuritis purple = atelectasis Note: structures inside the lung lobes have been UVd and include AO maps.
