Applicants have created systems, methods, and computer readable media for verifying the accuracy of medical treatment in accordance with a treatment plan. The method can include the step of receiving medical treatment data including one or more treatment fields and the step of comparing a sample of a segment of treatment plan data with a sample of a first treatment field. The method can further include the step of comparing the segment with the first treatment field if the compared samples match within a first tolerance and the step of generating output data including the results of the step of comparing the segment with the first treatment field if a match occurs within the first tolerance. Through the inventions described herein, a software-based quality assurance analysis can be performed to quickly and accurately verify a patient's dosage in a variety of medical treatments including intensity-modulated radiation therapy.
