| 中文摘要 | γ射线CT是近年来应用日益广泛的一种非破坏性放射性废物桶检测技术。该技术能够实现对被测对象中放射源的识别、定量与定位,为放射性废物的进一步处置和管理提供依据。本文简述了γ射线CT放射性废物桶检测技术的应用背景,对其数学模型、系统设计、主要性能指标及其影响因素等进行了总结和阐述,详细介绍了其放射性活度图像重建算法与校正方法等关键技术的相关研究进展,并对其未来的发展方向进行了展望。; γ-ray CT is one of the non-destructive technologies increasingly applied for radioactive waste assay in recent years. The radioactive sources in the target objects can be identified, quantitified and located by γ-ray CT, offering the bases for further disposal and management of the radioactive waste. In this paper, the application background of γ-ray CT for radioactive waste assay is briefly described, and the mathematical models, system designs of the technology are summarized, as well as its main performance indices and influencing factors. Furthermore, the research developments in key techniques about the algorithms and correction methods for radioactivity image reconstruction are introduced in detail. Finally, an outlook to future developments of the technology is given. |
