, Xu Zhen-Yu1, He Ya-Bai1 Concentration image reconstruction for Gaussian model by traditional and modified ART with a total of 300 projection rays scattered between 0° and 180°. Panels (a) and (b) show original and reconstructed concentration distribution by TM, and panels (c) and (d) display original and reconstructed concentration distribution by MM, respectively.
