New ReGA Framework Enhances Pelvic Bone Segmentation Models

Researchers have developed a novel framework called ReGA for test-time adaptation of pelvic bone segmentation models. This closed-loop system addresses challenges like boundary degradation and anatomical inconsistency that arise when models trained in one hospital setting are deployed in another. ReGA utilizes a dynamic reliability-guided approach, incorporating a segmentation inference consistency evaluation (SICE) to measure region overlap and boundary deviation, and a confidence-weighted contrastive learning strategy to enforce anatomical consistency. Experiments on three diverse datasets show that ReGA outperforms existing test-time adaptation methods, enabling effective adaptation of models to new clinical domains. AI
