摘要/Abstract

摘要： 围绕辐射等效仿真人体模型构建,提出了一种分层装配式快速成型方法。采用聚乳酸(PLA)、定制骨等效材料与聚氯乙烯(PVC)泡沫分别模拟软组织、骨组织与肺组织,通过结合熔融沉积成型(FDM)、浇筑成型及计算机数控制造(CNC)加工技术,分别实现软组织、骨组织和肺组织等部位的精确制作,并从CT值一致性、几何精度与成型效率等方面开展性能验证。结果表明,该方法在解剖结构还原性、组织等效性及制造周期控制方面均表现优异,可为辐射剂量模拟、放疗验证及防护评估等提供可靠的基准实验装备。

Abstract: A hierarchical assembly rapid prototyping method was proposed on the construction of radiation-equivalent physical phantoms. Polylactic acid (PLA), a customized bone-equivalent material, and polyvinyl chloride (PVC) foam were employed to simulate soft tissue, bone tissue, and lung tissue, respectively. Soft tissue, bone tissue, and lung tissue components are fabricated with high geometric fidelity through the integrated application of fused deposition modeling (FDM), investment casting, and computer numerical control (CNC) machining.Performance verification was conducted with respect to CT value consistency, geometric accuracy, and prototyping efficiency. The results indicate that the proposedmethod achieves excellent structural fidelity, tissue equivalence, and precise control over manufacturing cycle, thereby establishing a reliable benchmark platform for radiation dose simulation, radiotherapy validation, and radiation protection assessment.

Key words: radiation anthropomorphic phantom, rapid prototyping, tissue equivalence
