Alibaba Opensources ClinFusion: A Medical Multimodal Foundation Model
aigclink · x · 2026-08-01
Alibaba's DAMO Academy has open-sourced ClinFusion, a medical multimodal foundation model designed to tackle the unified processing of heterogeneous medical images. It enables AI assistants to comprehend lesion structures, communicate via natural language, and invoke external tools for assisted diagnosis.
Technical Highlights:
- Cascaded Vision Architecture: Unifies 2D/3D medical image understanding by combining various vision encoders, acting like a multi-disciplinary team of generalists, specialists, and 3D radiology experts.
- CaSL Fusion Mechanism: Progressively enhances base features with expert modules and aligns 3D data using 2D features, ensuring spatial characteristics accurately map to the language model.
- Clinical Workflow Integration: Supports agent tool use, allowing it to autonomously retrieve medical literature or invoke specific models (e.g., organ segmentation) during uncertain diagnoses.
The model achieved SOTA performance in a blind evaluation by radiologists across 300 real-world cases.
