A new generation of realistic, image-based anthropomorphic phantoms has been developed based on the reference masses and organ definitions given in the International Commission on Radiological Protection Publication 89. Specific absorbed fractions for internal radiation sources have been calculated for photon and electron sources for many body organs. Values are similar to those from the previous generation of 'stylized' (mathematical equation-based) models, but some differences are seen, particularly at low particle or photon energies, due to the more realistic organ geometries, with organs generally being closer together, and with some touching and overlapping. Extension of this work, to use these phantoms in Monte Carlo radiation transport simulation codes with external radiation sources, is an important area of investigation that should be undertaken.
基于国际放射防护委员会第89号出版物给出的参考质量和器官定义，已开发出新一代逼真的、基于图像的人体模型。针对许多身体器官，已计算出光子和电子源的内部辐射源的特定吸收分数。其值与上一代“程式化”（基于数学方程）模型的值相似，但由于器官几何形状更逼真，器官通常靠得更近，且存在一些接触和重叠，因此在低粒子或光子能量下会出现一些差异。将这项工作扩展到在具有外部辐射源的蒙特卡罗辐射传输模拟代码中使用这些人体模型，是一个应开展的重要研究领域。
