Abstract
System and method of determining whether a component of a radiation therapy system is operating within a dosimetric tolerance. The method can include the acts of 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.
