虚拟人体模型是辐射防护领域的一种基础工具,它可以结合蒙特卡罗程序来计算ICRP规定的防护量和ICRU规定的实用量与粒子注量、比释动能等物理量之间的转换系数,这些转换系数有的是实验无法测量的[1]。同时,虚拟人体模型还广泛应用于放射医学、空间辐射防护、探测器的标定等领域。1虚拟人体模型的发展历程虚拟人体模型经历了由简单数学模型到复杂体素模型的发展过程。1.1数学模型数学模型是用数学公式描述的简单几何体来
The Virtual Human Model is a fundamental tool in the field of radiation protection that can be combined with a Monte Carlo program to calculate the amount of protection specified by the ICRP and the conversion factor between the ICRU-specified utility and the physical quantities such as particle fluence, kerogen, etc. Some conversion coefficients can not be measured experimentally [1]. At the same time, the virtual human model is also widely used in radiology, space radiation protection, detector calibration and other fields. A virtual human model of the development process Virtual human model has gone from a simple mathematical model to the complex voxel model of the development process. 1.1 Mathematical Models Mathematical models are simple geometric equations described by mathematical formulas
