Helical tomotherapy (HT) is a form of intensity-modulated radiation therapy that is employed in total body irradiation (TBI). Because TBI targets the whole body, accurate setup positioning at the edge of the treatment volume is made difficult by the whole-body rotational posture. The purpose of this study is to clarify the tolerance for rotational setup error (SE) in the vertical direction. In addition, we perform a retrospective analysis of actually irradiated dose distributions using previous patients’ irradiation data.

旋转设置误差对使用螺旋断层疗法全身照射的影响

螺旋断层放疗 (HT) 是一种用于全身照射 (TBI) 的调强放射治疗形式。由于 TBI 以全身为目标,因此全身旋转姿势使得在治疗区边缘的准确设置定位变得困难。本研究的目的是阐明垂直方向的旋转设置误差 (SE) 的容差。此外,我们使用以前患者的辐照数据对实际辐照剂量分布进行了回顾性分析。
