Between July 2013 and August 2019, 22% of the imaging and radiation oncology core (IROC) spine, and 15% of the moving lung phantom irradiations have failed to meet established acceptability criteria. The spine phantom simulates a highly modulated stereotactic body radiation therapy (SBRT) case, whereas the lung phantom represents a low‐to‐none modulation moving target case. In this study, we assessed the contribution of dose calculation errors to these phantom results and evaluated their effects on failure rates.

剂量计算错误是 IROC 肺和脊柱幻影照射失败的一个组成部分。

2013 年 7 月至 2019 年 8 月期间，22% 的影像和放射肿瘤学核心 (IROC) 脊柱和 15% 的移动肺体模照射未能满足既定的可接受标准。脊柱体模模拟高度调制的立体定向放射治疗 (SBRT) 病例，而肺体模代表低至无调制的移动目标病例。在这项研究中，我们评估了剂量计算错误对这些幻像结果的影响，并评估了它们对故障率的影响。
