辐射等效仿真人体模型快速成型方法及性能初步验证
A rapid prototyping methodology for radiation-equivalent physical phantoms with preliminary performance verification
摘要
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.关键词
