| 摘 要： | 利用康普顿散射可以重建物质的电子密度图像。传统的逐点重建法算法简单，但实验装置复杂，且存在对焦误差，文章对传统的逐点重建成像方法进行了改进，提出了基于行扫描散射能谱的逐点重建方法，在此基础上用对称校正的方法对重建结果进行了改善，并给出了计算机仿真的结果。

| Abstract: | Compton scattering can be utilized for ele ct ron density imaging.The traditional point-by-point imaging modality is very simple,however,it needs complex experimental setup and there exist positioning error.In this paper,an improved point-by-point imaging method based on the line-scanning energy spectral data is proposed along with symmetric correction for the improvement of the reconstruction results.Some simulation results ar e presented in this paper. |
