New framework enhances Segment Anything Model for medical image segmentation

Researchers have developed SAM-DCE, a new framework designed to improve the prompt-free segmentation capabilities of the Segment Anything Model (SAM) for medical imaging. This approach addresses SAM's tendency to lose fine local details and create semantically ambiguous mask tokens when not guided by user prompts. SAM-DCE incorporates Spatial Representation Compensation (SRC) to retain anatomical evidence from intermediate ViT features and Semantic Token Calibration (STC) to enhance the consistency of foreground mask tokens. The framework refines these representations before they are processed by SAM's original token-to-mask mechanism, achieving a mean Dice score of 83.86% on the Synapse multi-organ CT dataset and outperforming existing CNN-, Transformer-, and SAM-based methods.
