Researchers have developed a new self-supervised learning framework called ANAUS for ultrasound images, which focuses on learning representations based on anatomical structures rather than generic image regions. This approach uses a prompt engine to delineate anatomy without requiring manual annotations. The framework employs a dual-policy learning paradigm to ensure feature invariance within anatomical regions while promoting discriminability between different structures and predicting corrupted regions to capture fine-grained details. Evaluations on six datasets show that ANAUS outperforms existing state-of-the-art methods and is computationally efficient for clinical use. AI
