| 中文摘要 | 阵列背散射成像是一种有发展潜力的辐射成像技术。与透射成像相比,阵列背散射图像数据校正较为复杂,涉及数据不一致性校正和系统响应曲线调整两个方面。基于阵列背散射成像系统的特点分析,应用蒙特卡罗仿真实验方法,归纳总结出1种增益归一化与斜率调整相结合的阵列背散射图像校正方法。利用该方法对仿真实验得到的数据进行校正,获得了较好的校正效果。; Backscatter imaging with a detector array(i.e.array backscatter imaging) is a radiation imaging technology which has great development potential.Being quite different from the transmission imaging,data correction in array backscatter imaging is a very complicated problem,including data variance correction and system response curve adjustment.Based on the characteristic analysis of the array backscatter imaging system and the Monte-Carlo simulation experiments,a new way combining gain normalization and slope adjustment was introduced to correct the image data in the array backscatter imaging.By using this method,a good result was obtained for the simulation data correction. |
