During treatment planning for head‐and‐neck volumetric‐modulated arc therapy (VMAT), manual contouring of the metal artifact area of artificial teeth is done, and the area is replaced with water computed tomography (CT) values for dose calculation. This contouring of the metal artifact areas, which is performed manually, is subject to human variability. The purpose of this study is to evaluate and analyze the effect of inter‐observer variation on dose distribution.

牙科金属伪影转换量对头颈部容积调制电弧疗法中剂量分布的影响

在头颈容积调制弧光治疗（VMAT）的治疗计划期间，对人造牙齿的金属假象区域进行了手动轮廓绘制，并用水计算机断层扫描（CT）值代替了该区域以进行剂量计算。手动执行的金属工件区域的轮廓绘制会受到人为变化的影响。本研究的目的是评估和分析观察者间差异对剂量分布的影响。
