Abstract

PURPOSE

Compare dose distributions of traditional versus conformal beam orientations in paranasal sinus malignancies.

MATERIALS AND METHODS

Maximum normal tissue doses, dose volume histograms (DVH), normal tissue complication probabilities (NTCP), and the percentage of each normal tissue receiving >80% of the average target dose (V80) were calculated.

RESULTS/CONCLUSIONS: Conformal planning reduced the V80 to the optic nerves and chiasm as well as the normal tissue maximum doses to the ipsilateral and contralateral optic nerves and chiasm, and mean NTCPs.

摘要

目的

比较传统射野方向与适形射野方向在鼻窦恶性肿瘤中的剂量分布。

材料与方法

计算正常组织的最大剂量、剂量体积直方图（DVH）、正常组织并发症概率（NTCP）以及接受平均靶剂量>80%的各正常组织的百分比（V80）。

结果/结论：适形计划降低了视神经和视交叉的V80以及同侧和对侧视神经及视交叉的正常组织最大剂量和平均NTCP。
