3 Combining complexity metrics to better predict VMAT deliverability

Introduction. Use of Volumetric Arc Therapy (VMAT) is constantly growing due to its ability to deliver highly conformal dose to the target faster than most of conventional techniques. However, complexity of VMAT plans has been shown to be directly linked with delivery accuracy which is one of the reasons why systematic pre-treatment QA are usually performed before clinical treatment. In order to reduce patient-specific QA workload, numerous studies have focused on complexity metrics to see whether it can be related with VMAT deliverability.
