Abstract :
We developed an image restoration method for an advanced Compton camera (ACC) making use of Compton scattering and recoiled electrons. In this paper, we simulated a system with two ACCs located perpendicular to each other with an Electron Gamma Shower ver.5 (EGS5) code, and reconstructed images with a modified source space tree algorithm. Moreover, we deblurred the reconstructed images with a parametric Wiener filter. The results of simulations confirmed the validity of our proposed methods.
