Design and making of a dual mode phantom for PET/CT performance testing

目的探讨PET/CT性能检测双模态体模的设计与制作。方法通过模拟人体组织形态,采用复合式结构设计,将PET测试功能模块和CT测试功能模块结合起来,使其二合一。结果在参考目前常用体模的基础上,制作了实用的、价格低廉的PET及CT检测都可使用的双模态体模。结论双模态体模可以实现“一模多用”,从而更方便简捷地应用于PET及CT性能检测。

Objective Explore the design and fabrication of a dual modal phantom for PET/CT performance testing.Methods By simulating the human tissue morphology,the PET test function module and CT test function module were combined by compound structure design to make them two in one.Results Based on the reference of the commonly used phantoms at present,a practical and inexpensive dual-mode phantom which can be used for both PET and CT examination was fabricated.Conclusion The dual-mode phantom can achieve“one mode and multiple uses”,so it is more convenient and simple to apply to PET and CT performance testing.
