Island blocking occurs in single-isocenter multiple-target (SIMT) stereotactic radiotherapy (SRS) whenever targets share multi-leaf collimator (MLC) leaf pairs. This study investigated the effect on plan quality and delivery, of reducing island blocking through collimator angle optimization (CAO). In addition, the effect of jaw tracking in this context was also investigated.

在 Varian Eclipse 治疗计划系统中使用准直器角度优化和颌骨跟踪进行基于 VMAT 的单等中心多目标立体定向放射外科手术，最多可处理六个目标

只要目标共享多叶准直器 (MLC) 叶对，就会在单等中心多目标 (SIMT) 立体定向放射治疗 (SRS) 中发生岛阻塞。本研究调查了通过准直器角度优化 (CAO) 减少孤岛阻塞对计划质量和交付的影响。此外，还研究了在这种情况下下颌跟踪的效果。
