Per-Organ Recall Control for CT Segmentation Under Domain Shift
Distribution-free risk control framework adds organ-specific recall guarantees to multi-organ CT segmentation models trained on AMOS dataset. Validates transfer robustness by auditing performance on RAOS, revealing that 7/12 organs exceed acceptable false-negative thresholds post-transfer. Critical for clinical deployment where missing pathology has zero tolerance.
