Effect of Scatter Photon to 60Co Container Inspection System
-
摘要: 用蒙特卡罗（EGSnrc）方法模拟计算集装箱（大型客体）CT检测系统60Co光子能谱，讨论和分析了该检测系统的客体散射光子对影像分辨率的影响，为进一步提高集装箱（大型客体）CT检测系统数字成像分辨率提供了理论依据.Abstract: The photon fluences for 60 CT container inspection system are calculated by using Monet Carlo method. The paper provides that these results of calculation for 60 photon fluences can give a correction method to increase CT image resolution.
