In breast cancer radiotherapy treatment with Volumetric Modulated Arc Therapy (VMAT), the respiratory motion may lead to underdosing of the target and overdosing of critical organs such as the heart and lungs. This study aims to investigate the effect of using Virtual Bolus with different thicknesses on VMAT plan quality for patients with 20 advanced left-sided breast cancers. The result of the study showed that using Virtual Bolus for VMAT treatment planning is a viable method to avoid any missing target coverage.
在使用容积旋转调强放疗（VMAT）治疗乳腺癌的过程中，呼吸运动会导致靶区剂量不足，以及心脏和肺部等重要器官剂量过高。本研究旨在探讨使用不同厚度的虚拟体模对 20 例左侧晚期乳腺癌患者 VMAT 计划质量的影响。研究结果表明，在 VMAT 治疗计划中使用虚拟体模是一种可行的方法，可以避免任何靶区覆盖的缺失。
