• Cancer patients receiving radiation therapy

• Patients at high risk of contrast allergy

• Head & neck tumor patients needing precise positioning

• Anxious patients needing shorter exam time

The Department of Radiation Oncology at Cathay General Hospital uses AI algorithms to accurately identify carotid arteries in non-contrast CT scans, providing precise references for radiation therapy simulation. Three key advantages: (1) improved image recognition shortens tumor delineation time; (2) slow contrast injection reduces allergy rates from 13% to 1.2%; (3) same-day online image verification ensures accurate tumor targeting. The technique is now routinely used: 113 AI-assisted identifications, 162 slow contrast simulations, and 4,097 online verifications annually. Presented at the ASQUA international conference, the hospital also holds MOHW Cancer Care Quality Certification (Excellent, valid 2020-2026). This innovation combines AI technology with quality management to deliver safe, personalized cancer care.
