| 摘 要： | 本文基于首都儿科研究所提供的中国儿童真实CT扫描图像建立了10岁中国儿童参考人面元体模。采用了多边形网格模型与NURBS曲面模型相结合的方法，建立了10岁中国儿童的多边形网格面元。体模包括85个器官，经过优化和调整，各组织和器官质量与GBZ/T 200 2-2007和亚洲参考人的参考值差异小于1%，各器官位置和形态符合中国儿童解剖学特征。该面元体模为10岁中国儿童剂量的准确计算提供了重要工具。

| Abstract: | 10-year-old Chinese pediatric reference boundary representation phantom based on CT images of Chinese children was developed in this paper. The mesh-type phantom using both polygon-mesh and NURBS surfaces was established. The phantom was divided into 85 organs. The mass of individual organ was adjusted to the GBZ/T 200 2—2007 and Asian reference man with the difference less than 1% after the optimization of organs. The shape and position of all organs are consistent with the anatomical characteristics of Chinese children. This phantom provides an effective tool to estimate the dose of 10-year-old Chinese children accurately. |
