System and method for virtual radiation therapy quality assurance

A system for generating predictive passing rates for radiation therapy comprising:

• a data-processing system;
• a plan database comprising one or more radiation treatment plans for a first patient;
• a passing rate database comprising one or more passing rates associated with each of the radiation treatment plans in the plan database;
• and
• a predictive model for generating predictive passing rates based on the plan database and the passing rate database;
• wherein the data-processing system receives the one or more radiation treatment plans from the plan database and the one or more passing rates from the passing rate database and applies the predictive model to organ data for a second patient and to one or more radiation treatment plan parameters for the second patient to generate one or more predicted passing rates for the one or more radiation treatment plan parameters for the second patient.
