| 中文摘要 | 由于探测器对散射点所张立体角受到限制,在阵列背散射成像中实现有机物加亮效应相对困难。本文通过蒙特卡罗仿真方法,对这一问题进行研究,指出了实现或增强加亮效应的三种解决途径———改变探测器位置、改变探测器工作方式和选择合适的入射射线能量,并提出一种阵列背散射装置的构想。; Because of the limitation of solid angle of detector at the scattering point,it is difficult to achieve the highlighting effect of organic materials in Compton backscatter imaging system with detector array.This paper studies the problem with Monte Carlo simulation method and indicates three solutions including changing the angle of detecting,changing the working mode of detector and selecting the appropriate energy of incident ray.In the end,this paper suggests a new Compton backscatter imaging system. |
