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

6MV和10MV扁平化和扁平化无滤波器光束在全脑放射治疗中的影响——一项治疗计划研究。

前言:研究6MV、10MV平坦束(FB)和平坦无滤波束(FFF)在体积弧治疗(VMAT)全脑放疗(WBRT)中的影响。材料与方法:随机选取全脑放疗患者20例，剂量处方为30Gy，分10次给药。绘制计划靶体积(PTV)和危险器官(OAR)。在Eclipse治疗计划系统中为每位患者生成6MV FB、6MV FFF、10MV FB和10MV FFF四个VMAT计划。注意到PTV的覆盖率、OAR的剂量和交付监测单位。结果:6MV FB和FFF波束计划差异有统计学意义(p
