Synopsis

Keywords: Analysis/Processing, AI/ML Software, Foundation model, Segmentation, Domain Adaptation

Motivation: Vision foundation models have demonstrated impressive capabilities in natural image segmentation. However, their application to MRI remains challenging due to the lack of domain-specific adaptation.

Goal(s): Introduce an adaptation method that effectively adapts vision foundation models for MRI image segmentation, without model training or fine-tuning.

Approach: We propose a training-free adaptation pipeline that emulates human analogical thinking, leveraging few-shot examples to rapidly adapt the Segment Anything Model (SAM) to medical imaging.

Results: The proposed approach demonstrates superior performance over both the original SAM and its advanced variant, SAM2, in terms of quantitative metrics and qualitative analysis.

Impact: Our training-free adaptation method circumvents the need for laborious data collection and labeling, providing a generalizable solution for applying vision foundation models to medical image segmentation.
