Stereotactic ablative body radiotherapy (SABR) of primary kidney cancers is confounded by motion. There is a risk of interplay effect if the dose is delivered using volumetric modulated arc therapy (VMAT) and flattening filter‐free (FFF) dose rates due to target and linac motion. This study aims to provide an efficient way to generate plans with minimal aperture complexity.

关于降低肾脏SABR的孔径复杂度

原发性肾癌的立体定向消融身体放疗（SABR）与运动混淆。如果由于靶标和直线加速器的运动而使用体积调制电弧疗法（VMAT）和扁平无过滤器（FFF）剂量率输送剂量，则存在相互作用的风险。这项研究旨在提供一种有效的方法，以最小的孔径复杂度生成计划。
