Abstract
Introduction: To study the impact of 6MV and 10MV flattened beam (FB) and flattening filter free beam (FFF) in whole brain radiotherapy (WBRT) by using volumetric arc therapy (VMAT).Materials and Methods: Twenty whole brain radiotherapy patients were selected randomly and the dose prescription was 30Gy, which is delivered in 10 fractions. Planning target volume (PTV) and organ at risk (OAR’S) were contoured. The four VMAT plans, like 6MV FB, 6MV FFF, 10MV FB and 10MV FFF were generated for each patient in Eclipse Treatment Planning system. PTV coverage, OAR’s doses and delivery monitoring units (MU) were noted.Results: The 6MV FB and FFF beam plan were statistically significant (p
