Plot of non-uniformity versus recovery coefficient (rod diameter is 3 mm) for various reconstruction algorithms, such as FBP, FBP-3DRP, OSEM2D, and OSEM3D-MAP reconstruction with filters. All data were presented for (a) partially corrected data, (b) AC corrected, and (c) AC and SC corrected data. The optimal criteria (0.9 < RC < 1.0 and NU < 10%) are marked in the red box. 3DRP: FBP-3DRP, MAP: OSEM3D-MAP.
