1. A method of detecting a delivery error in a radiation delivery device, the method comprising using a computer to carry out the steps of:
- generating a treatment plan for a patient, the treatment plan including an intended fluence;
delivering radiation to the patient according to the treatment plan;
acquiring output fluence information from the radiation delivery device after delivery of the treatment plan;
comparing the output fluence information and the intended fluence to determine a fluence variance; and
applying a dose calculation algorithm to the fluence variance to generate a dose variance map.

Abstract
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.
