本文描述了利用中国政府和国际原子能机构(IAEA)推荐的参考数据，为中国人口建立一套基于网格和年龄相关的人体模型。现有的网格基于RPI成年男性(RPIAM)和RPI成年成年女性(RPI-AF)体模变形形成新的体模解剖数据来显示中国个人的身高和体重（包括5岁男性,5岁女,10岁男性,10岁女性,15岁男,15岁女性,成年男性和成年女性，分别命名我为USTC-5 M, USTC-5F, USTC-10M, USTC-10F, USTC-15M, USTC-15F USTC-AM和USTC-AF）。为保证准确性，每个模型中均有超过120个器官/组织被调整以匹配中文参考参数，质量误差在0.5%以内。为了证明其有效性，将这些新的体模与GE LightSpeed Pro 16多检测器计算机断层扫描(MDCT)扫描仪的充分验证模型和基于GPU的ARCHER Monte Carlo代码相结合，以计算CT检查产生的器官剂量。然后将成人模型的器官剂量与相同条件下RPI-AM和RPI-AF的数据进行比较。RPI体模的吸收剂量和有效剂量均低于体型较小的中国科大成人体模。并对不同年龄和性别的剂量进行了比较。研究发现，青少年比成年人受到更多的辐射剂量。这种中国特有的体模显然更适合用于针对中国人的器官剂量研究，而不是针对西方人群的。正如已经证明的，来自特定年龄的中国体模的数据可以帮助CT操作员和设计者优化图像质量和剂量。

The existing grid based on RPI adult male (rpiam) and RPI adult female (rpi-af) phantom deformation to form a new phantom anatomical data to show the height and weight of Chinese individuals (including 5-year-old male, 5-year-old female, 10-year-old male, 10-year-old female, 15-year-old male, 15-year-old female, adult male and adult female, named me ustc-5m, ustc-5f, ustc-10m, ustc-10f, ustc-15m, ustc-10m, ustc-10f, ustc-15m, ustc-5f, ustc-10m, ustc-10m, ustc-10f, Ustc-15f, ustc-am and ustc-af). To ensure the accuracy, more than 120 organs / tissues in each model were adjusted to match the Chinese reference parameters, and the quality error was within 0.5%. To prove its effectiveness, these new phantom were combined with the full validation model of Ge Lightspeed Pro 16 multi detector computed tomography (MDCT) scanner and GPU based Archer Monte Carlo code to calculate the organ dose generated by CT examination. Then the organ dose of adult model was compared with rpi-am and rpi-af data under the same conditions. The absorbed dose and effective dose of RPI model were lower than that of the smaller adult model of China University of science and technology. The doses of different ages and genders were compared. The study found that teenagers are exposed to more radiation than adults. This Chinese specific phantom is obviously more suitable for organ dose research for Chinese people than for western people. As has been demonstrated, data from age-specific Chinese phantom can help CT operators and designers optimize image quality and dose.
