    摘要： 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.

    摘要： A system and method of evaluating dose delivered by a radiation therapy system using a marker that indicates motion. The marker is associated with the patient. In one method of operation, the method includes delivering radiation to the patient, monitoring motion of the marker during the delivering radiation, and evaluating a dose delivered to the patient based at least in part on the motion of the marker. In another method of operation, the method includes delivering radiation to the patient, obtaining information relating to the delivery of radiation, estimating dose to the marker based at least in part on the information, acquiring dose received by the marker, and comparing the received dose with the estimated dose.

    摘要： A dose calculation tool operable to generate a variance map that represents a dose uncertainty. The variance map illustrates on a point-by-point basis where high uncertainty in the dose may exist and where low uncertainty in the dose may exist. The dose uncertainty is a result of an error in one or more data parameters related to a delivery parameter or a computational parameter.
