基于物理体模CT图像的1岁儿童体素体模构建

Construction of 1-year-old Child Voxel Phantom Based on CT Image of Physical Phantom

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Model704-D相匹配。

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.
