RibFrac
RibFrac is a chest-abdomen CT benchmark for rib fracture detection, instance segmentation and fracture-type classification. It provides voxel-level fracture masks and clinical fracture categories.
The public dataset is available after free registration through the RibFrac Grand Challenge platform. The project states that the work is licensed under the Creative Commons Attribution-NonCommercial 4.0 International license.
The public challenge dataset contains 660 CT scans from 660 unique patients and approximately 5,000 rib fractures. It includes 420 training scans, 80 validation scans and 160 evaluation scans. Training and validation annotations are available, while the evaluation labels are hidden. Ribs are not available in the current anatomy enum, so anatomy is recorded as other. The challenge's dataset subpage is not reachable without signing in, so the link points to the challenge home page; the data itself is behind registration.
