Doctors at Memorial Sloan Kettering Cancer Center in New York are using artificial intelligence (AI) to make radiation therapy more precise and effective for cancer patients. The technology is helping doctors target tumors more accurately while reducing harm to healthy tissues.

AI models are being trained to understand how organs move and change shape inside the body due to breathing, digestion, and other natural processes. By creating digital twins of patients’ internal anatomy, doctors can simulate organ movement and plan radiation treatments more effectively. This makes it possible to deliver the right amount of radiation to tumors while avoiding unnecessary exposure to nearby organs.

The new system also assists doctors by speeding up the process of analyzing scans. Instead of manually outlining organs and tumors, AI provides an initial map that doctors can quickly refine. It also tracks how much radiation has been delivered to different parts of the body and measures tumor response in real time, giving doctors the chance to adjust treatment when needed.

This AI-assisted method is already being used for patients with head and neck, lung, brain, liver, pancreatic, and prostate cancers. Experts believe the technology will make cancer care more personalized, accurate, and adaptable, ultimately improving treatment outcomes for patients worldwide.
