Photon Beam Commissioning and Rapid Arc Prerequisite QA of Varian Unique Performance Low Energy Linear Accelerator (LINAC)

The aim of this study is to present the review of commissioning and Rapid Arc prerequisite QA results of Varian unique performance low energy linear accelerator (linac), was introduced by Varian Medical system (Palo Alto, CA, USA). The acceptance test and commissioning were performed for 6 MV photon beam and for the multileaf collimator (MLC). Percentage Depth Dose, Surface dose, Dose Profiles (In-plane, Cross-plane and Diagonal), Flatness, Symmetry, field size, Penumbra, Couch Sag, Couch transmission factor, MU Linearity, Beam Quality, Collimator Transmission, Photon leakage, MLC transmission factors were measured. Rapid Arc Commissioning and QA procedures specific to RapidArc delivery systems have been proposed using integrated images from an Electronic Portal Imaging Device (EPID). It has been observed that the outcome of a commissioning beam data generation fully complies with vendor specification and published literature.
