Physical anthropomorphic phantoms have been utilized for a variety of dosimet- ric studies across a range of procedures utilizing diagnostic imaging equipment. Unfortunately, these phantoms are often limited to a single reference size, which often may not be representative of the patient population at large. This work set out to develop an adipose tissue-equivalent substitute material that could be used to create low cost physical additions for existing anthropomorphic phantoms. Using commercially available products, a methodology was developed to accomplish this, and an addition was built to create a 90th percentile by weight phantom from an existing 50th percentile model. This methodology can easily be used to expand the utility of existing anthropomorphic phantoms in order to better represent patients of various body morphologies, and investigate the effects of patient size in diagnostic procedures.
人体物理模型已被广泛应用于各种利用诊断成像设备的剂量学研究中。不幸的是，这些模型通常仅限于单一的参考尺寸，而这通常可能无法代表大多数患者群体。本研究旨在开发一种脂肪组织等效替代材料，可用于为现有的人体模型添加低成本的物理组件。本研究使用市售产品开发了一种实现该目标的方法，并构建了一个附加组件，以将现有的第 50 百分位模型体重增加到第 90 百分位。这种方法可以方便地扩展现有人体模型的应用范围，以更好地代表各种体型的患者，并研究患者体型对诊断程序的影响。
