Key Points:
1. Breakthrough in Medical Imaging:
• Researchers at Hong Kong University of Science and Technology (HKUST) developed an AI-powered algorithm that enables 3D anatomical reconstructions using only 2–4 standard X-ray images. Hong Kong has active participation in APSC initiatives, including the Scientific Advisory Board and the ASPIRE Network, which focuses on regional collaboration in areas like data sharing and clinical trials.
2. Radiation Dose Reduction:
• The new method reduces radiation exposure by 95%–99%, compared to traditional CT scans, making it significantly safer for patients.
3. Speed and Efficiency:
• The algorithm completes the 3D imaging process in under 1 minute, facilitating faster diagnosis and surgical planning while reducing imaging costs.
4. Scan Accuracy:
• The new AI algorithm can rebuild 3D images of bones and organs using only 2 to 4 regular X-ray images.
• It works almost as accurately as a CT scan — about 97% match — but with much less radiation.
• These 3D bone images help doctors plan surgeries better, especially in orthopedics (bone surgery).
• The technology can also support 3D printing of bone implants, helping patients who need fast or complex bone repairs.
• Instead of waiting days for CT scans and manual work, the AI can make a 3D bone model in under 30 seconds.
This means doctors can save time, reduce costs, and keep patients safer from radiation — all while getting highly accurate images of the bones they need to treat.
• Full clinical implementation expected within the next year, pending safety and efficacy confirmation.
