Researchers have developed a new framework called M2DINO, built on DINOv3, to improve the generalizability of ultrasound foundation models. The study systematically analyzed how different task aggregation strategies impact performance across 27 ultrasound tasks, considering segmentation, classification, detection, and regression. Findings indicate that the effectiveness of combining tasks depends heavily on the scale of available training data, with all-task unified training showing more consistent results than clinically-grouped approaches, especially in low-data scenarios. The research highlights that task sensitivity varies by type, with segmentation tasks showing the most significant performance drops. AI
