ABSTRACT
Machine-specic QA encompasses procedures to verify the performance of the equipment parts involved in modulated arc treatment delivery separately and in combination. e procedures for machine-specic QA can, to a large degree, be identical to or derived from the procedures used in commissioning. e procedures should include tests to investigate the extreme limits of behavior, as well as the moderate (more commonly used) behavior. e machine-specic QA procedures should be part of a QA program with schedules for daily, weekly, monthly, and yearly procedures.
