Due to multiple beamlets in the delivery of highly modulated volumetric arc therapy (VMAT) plans, dose delivery uncertainties associated with small‐field dosimetry and interplay effects can be concerns in the treatment of mobile lung lesions using a single‐dose of stereotactic body radiotherapy (SBRT). Herein, we describe and compare a simple, yet clinically useful, hybrid 3D‐dynamic conformal arc (h‐DCA) planning technique using flattening filter‐free (FFF) beams to minimize these effects.

一种简单但新颖的混合动力共形电弧治疗计划,该计划通过展平无过滤器束用于肺部立体定向放射治疗。

由于高剂量容积弧光治疗(VMAT)计划的递送中存在多个子束,因此在使用单剂量立体定向身体放射疗法治疗活动性肺部病变时,可能会担心与小剂量剂量学和相互作用影响相关的剂量递送不确定性( SBRT)。本文中,我们描述并比较了一种简单但临床上有用的混合3D动态共形弧(h-DCA)规划技术,该技术使用了平整无滤波器(FFF)光束来最大程度地减少这些影响。
