        abstract = {The objective of this study is comparing the planned and delivered Dose Volume Histogram (DVH) for Volumetric Modulated Arc Therapy (VMAT) patients. Using “DVH 4D” option provided by the software Veri Soft with the help of Octavius 4D phantom, DVH of all selected plans are compared. The tool DVH is used to compare doses from different plans or structures. The DVH curve is a plot of graph showing percentage volume of structure on Y-axis and dose in term of Gy on X-axis. VMAT techniques that delivered conformal radiation to the target volume. These techniques require complex Treatment Planning System (TPS) algorithms as well as sophisticated irradiation methods. As a result, the use of quality assurance tools for the verification of the planned dose distribution prior to the treatment of the patient is required for all VMAT cases. In this study, we have used OCTAVIUS detector 729, which is a 2D array of ion chambers used for pretreatment verification and QA. All the measurement is done in Elekta Versa HD Linear accelerator. For this study Ca. Breast, Head and neck case, Pelvic, were selected and planned with VMAT. Compared the dose obtained from TPS and from the patient specific QA.},
