Abstract:
1. A method of determining whether a component of a radiation therapy system is operating within a dosimetric tolerance, the method comprising: generating a treatment plan for a patient, the treatment plan specifying a radiation amount to be delivered to the patient; delivering radiation to the patient according to the treatment plan; obtaining feedback during the delivery of radiation, the feedback related to one of a position, a velocity, and an acceleration for one of a multi-leaf collimator, a gantry, a couch, and a jaws; generating a mathematical model based on the feedback for one of the multi-leaf collimator, the gantry, the couch, and the jaws; calculating a delivered dose amount based on the mathematical model and treatment plan information; calculating a deviation in dose between the radiation amount specified in the treatment plan and the delivered dose amount; and determining whether the deviation in dose is within a dosimetric tolerance for the one of the multi-leaf collimator, the gantry, the couch, and the jaws.
