BoneAgeTW2: Open-Source System Automates Tanner-Whitehouse 2 Skeletal Maturity Assessment
BoneAgeTW2 has been introduced by researchers as the inaugural fully open-source platform designed to automate the complete Tanner-Whitehouse 2 (TW2) protocol for evaluating skeletal maturity. Utilizing YOLOv8, the system identifies and locates 20 bones in hand radiographs, employing an EfficientNet-B3 backbone with 20 separate classification heads to simultaneously determine maturation stages (A-I) for each bone. It produces clinical PDF reports featuring interactive Gaussian distribution curves for all bones, facilitating comparisons with population standards. The model was developed using the RSNA Pediatric Bone Age Challenge dataset, which includes 12,611 hand radiographs, and applies a pseudo-labeling technique to extract individual stage labels from overall bone age annotations. The entire codebase is accessible on GitHub.
Key facts
- BoneAgeTW2 is the first fully open-source system for automating the complete TW2 protocol.
- The system uses YOLOv8 for detection and localization of 20 hand bones.
- An EfficientNet-B3 backbone with 20 independent classification heads assigns maturation stages (A-I).
- Clinical PDF reports include interactive Gaussian distribution curves for all 20 bones.
- Trained on the RSNA Pediatric Bone Age Challenge dataset (12,611 hand radiographs).
- Pseudo-labeling strategy derives per-bone stage labels from global bone age annotations.
- The codebase is publicly available on GitHub.
- The system is end-to-end, from detection to report generation.
