人体内辐射剂量的精确模拟计算需要建立精确模拟人体各种组织器官的人体模型。该文依据中国数字人项目的人体彩色切片照片数据,建立了中国参考人数字体素体模。它采用数百万至上千万个立方体体素描述了79种组织和器官,满足ICRP(International Commission on Radiologi-cal Protection)2007年建议书中组织权重因子的技术要求,并反映了中国人体貌特征,为得到适用于中国人的剂量学参数提供了技术基础。该文详述了中国参考人数字体素体模的建立过程,并将中国参考人男性数字体素体模分别应用在外照射剂量学和内照射剂量学的研究中。该研究对于促进我国人员辐射剂量评价工作具有一定的积极意义和应用价值。
An accurate simulation of the radiation dose in the human body requires the creation of a human model that accurately models various tissues and organs of the human body. Based on the human color slice photo data of Chinese digital human project, this paper establishes the Chinese reference digital voxel phantom. It uses millions to millions of cubes voxels to describe 79 kinds of tissues and organs to meet the technical requirements for tissue weighting factors in the 2007 ICRP (International Commission on Radiologic-cal Protection) recommendations and reflects the Chinese physical appearance , Provided the technical basis for obtaining the dosimetry parameters suitable for Chinese. The paper details the process of establishing Chinese reference voxel phantom and applies the Chinese digital voxel phantom to external dosimetry and internal dosimetry. This research has certain positive and applied value to promote the radiation dose assessment of our country.
