【Introduction】
In July 2024, Shanghai Huibi Information Technology Co., Ltd. entered into a strategic collaboration with Shanghai Ruijin Hospital to jointly launch the "HuiYi" AI-assisted diagnostic system. The system covers 10 major categories of diseases, including pulmonary nodules and diabetic retinopathy, and has been deployed in 8 primary care hospitals. Preliminary results show diagnostic accuracy on par with that of top-tier hospitals.
I. Technical Highlights: Enabling AI to Interpret Medical Images
- Multi-Disease One-Stop Detection:
Utilizing a multi-task learning framework, a single CT scan can simultaneously screen for five types of abnormalities, including pulmonary nodules and mediastinal lymph nodes.
Detection rate for nodules larger than 2mm reaches 99.2% (based on NMPA test data). - Enhanced Interpretability:
Features an innovative dual visualization system combining "heat maps + probability trees" to intuitively display the basis for lesion determination. - Lightweight Deployment:
Supports mobile app integration, enabling rural doctors to access top-tier diagnostic recommendations via smartphones.
II. Real-World Impact: A Case Study of a County Hospital in Yunnan
- Background:
The hospital’s imaging department had only two radiologists, handling over 150 CT scans daily, with a misdiagnosis rate of 15%. - Transformation:
- After AI implementation, diagnosis time per case dropped from 30 minutes to 3 minutes.
- Corrected 42 major misdiagnoses (including 3 early-stage lung cancers).
- Enabled real-time collaboration with Shanghai experts via a 5G remote consultation platform.

III. Social Value: Breaking Down Barriers in Healthcare Resources
Huibi Information simultaneously launched the "Thousand Counties Inclusive Plan":
- Provide basic AI diagnostic tools free of charge to 1,000 county-level hospitals by 2025.
- Train 5,000 primary care doctors in partnership with non-profit organizations.
- Develop dialect-based voice interaction features to serve ethnic minority regions.
【Conclusion】
"AI is not meant to replace doctors, but to make high-quality healthcare accessible to all," emphasized Dr. Wang Lei, Chief Medical Scientist at Huibi Information. The system has already received Class III medical device certification from the NMPA and is expected to be included in the national medical insurance procurement list by the end of this year.
