对于I期肺癌患者，大剂量常规立体定向全身放射治疗(SBRT)一般需要30-45分钟/次。用于计划和交付的新型体积强度调制弧形疗法(RA)使三名采用不同分割方案的患者能够更快地接受治疗。这降低了碎块内运动的风险，对患者更友好。此外，与使用10个静态非共面野的常规计划相比，RA计划在PTV周围实现了更好的剂量一致性，并减少了胸壁剂量。(C)2009爱思唯尔爱尔兰有限公司。保留所有权利。放射治疗与肿瘤学93(2009)122-124
The delivery of high dose conventional stereotactic body radiotherapy (SBRT) for patients with stage I lung tumors generally takes 30-45 min per fraction. The novel volumetric intensity-modulated arc therapy (RA) for planning and delivery enabled much faster treatment for three patients with different fractionation schemes. This reduces the risk of intrafraction motion and is more patient friendly. In addition, in comparison to the conventional plans using 10 static non-coplanar fields, RA plans achieved superior dose conformity around the PTV and reduced chest wall doses.
