康普顿背散射成像中的有机物加亮效应研究

Study On Highlighting Effect Of Organic Materials In Compton Backscatter Imaging

康普顿背散射成像技术与透射成像相比具有使有机物自动加亮的特点,因此更适合于对爆炸物、毒品等违禁物品的检测。本文通过蒙特卡罗仿真方法,分析了影响有机物加亮效应的若干因素(包括入射射线能量、被检物体尺寸、探测器大小与位置、探测器工作方式),为背散射成像系统设计提供了参考。

Compare with the transmission imaging, Compton backscatter imaging has an advantage of highlighting the organic materials, so it is more appropriate for inspection of contraband such as explosives, drug eta This paper analyses several factors which affect the highlighting effect of organic materials with Monte Carlo simulation method,including energy of the incident ray, dimension of the target material, dimension and position of detector, working mode of detector. The results help to design Compton baekseatter imaging system designing.
