本文报告了用于构建剂量测定研究的拟人模型的方法和材料，改进了Jones等人[Med Phys. 2006;33（9）：3274-82]先前描述的方法和材料。迄今为止，所描述的方法已成功地用于创建一系列的三个不同的成人幻影在佛罗里达大学（UF）。所有体模均使用设计用于在诊断光子能量下模拟人体组织的材料在5 mm横向切片中构建：软组织等效替代物（STES）、肺组织等效替代物（LTES）和骨组织等效替代物（BTES）。虽然BTES的配方与Jones等人[Med Phys. 2003;30（8）：2072-81]开发的先前环氧树脂化合物相比保持不变，但STES和LTES均使用氨基甲酸酯基化合物进行了重新设计，形成了柔韧的组织等效材料。选择这些聚氨酯基材料的部分原因是为了提高体模的耐久性和更容易容纳真实的时间剂量计。生产过程也得到了简化，使用自动加工系统，根据原始分割的计算机断层扫描（CT）数据集，从位图图像中创建体模切片模具。包括关于新组织等效材料的信息，以及构建过程和完成体模的图像。PACS编号：87.53.Bn
This paper reports on the methodology and materials used to construct anthropomorphic phantoms for use in dosimetry studies, improving on methods and materials previously described by Jones et al. [Med Phys. 2006;33(9):3274–82]. To date, the methodology described has been successfully used to create a series of three different adult phantoms at the University of Florida (UF). All phantoms were constructed in 5 mm transverse slices using materials designed to mimic human tissue at diagnostic photon energies: soft tissue‐equivalent substitute (STES), lung tissue‐equivalent substitute (LTES), and bone tissue‐equivalent substitute (BTES). While the formulation for BTES remains unchanged from the previous epoxy resin compound developed by Jones et al. [Med Phys. 2003;30(8):2072—81], both the STES and LTES were redesigned utilizing a urethane‐based compound which forms a pliable tissue‐equivalent material. These urethane‐based materials were chosen in part for improved phantom durability and easier accommodation of real‐time dosimeters. The production process has also been streamlined with the use of an automated machining system to create molds for the phantom slices from bitmap images based on the original segmented computed tomography (CT) datasets. Information regarding the new tissue‐equivalent materials, as well as images of the construction process and completed phantom, are included. PACS number: 87.53.Bn
