Auditable agentic AI for evidence-grounded thyroid ultrasound diagnosis and reporting
Haifan Gong, Shiyu Chen, Bodong Wang +11
Thyroid ultrasound diagnosis requires coordinated lesion localization, measurement, risk stratification and reporting, yet most AI systems address these tasks in isolation and prov…
Semantically Calibrated Evidence Composition for CT Vision-Language Learning
Guoliang You, Haifan Gong, Xiaomeng Chu
Learning transferable representations from CT-report pairs requires combining whole-volume context with anatomy-specific evidence. Existing methods typically emphasize either globa…
Learning How Much, Not Just What: Cross-Patient Burden Order for CT Vision-Language Pretraining
Guoliang You, Haifan Gong, Xiaomeng Chu
Volumetric CT vision-language pretraining learns 3D representations from scan-report pairs, but global and anatomy-aware objectives supervise only correspondence: they establish wh…
DreamReg: Belief-Driven World Model for 2D-3D Ultrasound Registration
Luoyao Kang, Yuelin Zhang, Jiwei Shan +3
Ultrasound (US) is widely used for surgical navigation, yet real-time registration between intraoperative 2D slices and preoperative 3D volumes remains challenging due to partial o…
Cross-Modal Self-Attention with Multi-Task Pre-Training for Medical Visual Question Answering
Haifan Gong, Guanqi Chen, Sishuo Liu +2
Due to the severe lack of labeled data, existing methods of medical visual question answering usually rely on transfer learning to obtain effective image feature representation and…
