Within the brachytherapy community, many phantoms are constructed in-house, and less commercial development is observed as compared to the field of external beam. Computational or virtual phantom design has seen considerable growth; however, physical phantoms are beneficial for brachytherapy, in which quality is dependent on physical processes, such as accuracy of source placement. Focusing on the design of physical phantoms, this review paper presents a summary of brachytherapy specific phantoms in published journal articles over the last twenty years (January 1, 2000 – December 31, 2019). The papers were analyzed and tabulated by their primary clinical purpose, which was deduced from their associated publications.

A substantial body of work has been published on phantom designs from the brachytherapy community, but a standardized method of reporting technical aspects of the phantoms is lacking. In-house phantom development demonstrates an increasing interest in magnetic resonance (MR) tissue mimicking materials, which is not yet reflected in commercial phantoms available for brachytherapy. The evaluation of phantom design provides insight into the way, in which brachytherapy practice has changed over time, and demonstrates the customised and broad nature of treatments offered.

近 20 年来近距离放射治疗物理模型的回顾：临床目的和未来要求


在近距离放射治疗领域，许多体模是在内部构建的，与外部光束领域相比，观察到的商业开发较少。计算或虚拟模型设计有了相当大的增长；然而，物理体模对于近距离放射治疗是有益的，近距离放射治疗的质量取决于物理过程，例如源放置的准确性。本文重点关注物理体模的设计，总结了过去二十年（2000年1月1日至2019年12月31日）发表的期刊文章中近距离治疗特定体模的摘要。这些论文根据其主要临床目的进行了分析和列表，这些目的是从相关出版物中推断出来的。


近距离放射治疗界已经发表了大量关于体模设计的工作，但缺乏报告体模技术方面的标准化方法。内部模型开发表明人们对磁共振 (MR) 组织模拟材料越来越感兴趣，但这尚未反映在可用于近距离放射治疗的商业模型中。对体模设计的评估提供了对近距离放射治疗实践随时间变化的方式的深入了解，并展示了所提供治疗的定制性和广泛性。
