This work is concerned with the comparison of two different dynamic conformal arc therapy (DCAT) stereotactic radiosurgery (SRS) planning systems, namely Eclipse and BrainLab Elements. The creation of an SRS plan is an involved process with many parameters to be considered and the treatment efficacy is sensitive to the accuracy of its delivery. As a result, the process of effective plan creation with acceptable normal tissue and organ at risk (OAR) sparing can be time consuming. The Elements treatment planning system (TPS) offers a streamlined approach to creating cranial SRS plans. The intention of this study is to dosimetrically compare each system to understand any potential gains in utilizing the Elements TPS.
