Description
Fada Guan and ten co-authors tested in 2024 a faster way to check whether a radiation plan made for one treatment machine fits its twin. Cancer centers buy beam-matched machines so patients can switch mid-course when one breaks down. Standard checks are slow, so the team tried a three-dimensional gamma score, computed with an open software kit.
Plans for many disease sites were rebuilt for the second machine and compared dose by dose. The gamma score flagged real differences beyond the usual point checks. A passing score gives clinics confidence to move a patient without replanning from scratch.
