Abstract
IROC-Houston recalculated over 250 head and neck phantom irradiations performed between 2012 and 2016 using a customized independent calculation system that was modeled after IROC-Houston linear accelerator measurement reference data. Dose recalculations that were substantially more accurate than the institution’s calculations suggested that the institution had treatment planning system calculation errors. Among all recalculations, 17% revealed such errors; among irradiations that failed IROC-Houston criteria, 68% had such errors.
