We quantitatively estimated dosimetric variations due to interfraction organ deformation in multi-fractionated high-dose-rate brachytherapy (HDRBT) for cervical cancer using a novel surface-based non-rigid deformable registration. As the number of consecutive HDRBT fractions increased, simple addition of dose-volume histogram parameters significantly overestimated the dose, compared with distribution-based dose addition.
我们使用一种新型的基于表面的非刚性可变形配准方法，对宫颈癌多分割高剂量率近距离放疗（HDRBT）中因分次间器官变形导致的剂量学变化进行了定量估计。随着连续HDRBT分割次数的增加，与基于分布的剂量相加相比，简单相加剂量体积直方图参数会显著高估剂量。
