| Abstract: | 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. |
