| 摘 要： | 本文介绍了基于1岁儿童物理体模（Model 704-D）的CT图像和中国成年男性参考人体素体模(CRAM)的1岁儿童体素体模（CPP01）的构建，包括通过对物理体模扫描得到OCP01体模（基于儿童物理体模的CT图像建立的一粗略的体素体模），进而构建和优化CPP01。该体素体模的各器官组织的质量与GBZ/T 200.2-2007所给数据的相对偏差约在5%以内，且其外部轮廓和主要器官的位置与Model 704-D相匹配。

| Abstract: | The construction of 1-year-old child voxel phantom （CPP01） based on the physical phantom CT image of Model 704-D and Chinese reference adult male phantom （CRAM） was introduced in this paper, including the construction of OCP01 （original computational phantom, which is a voxel phantom based on the CT image without optimization）, the construction and optimization of CPP01. The mass of individual organ of CPP01 is in accordance with that of GBZ/T 200.2-2007 with the relative error less than 5%, and CPP01 matches the physical phantom of Model 704-D in organ position. |
