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 .本文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 。
Compton scattering can be utilized for electron 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 are presented in this paper.
