Left: Reconstructed distribution of annihilation point spatial coordinates. The voxel size is equal to 5×5×5 mm3. Middle: Reconstructed image of six sources obtained while applying the TOF-FBP algorithm. The voxels: 1.8×1.8×2.9 mm3. Right: Reconstructed source placed at (x,y,z)=(1,0,0) cm. Each row show results with different resolution: CRT =10 ps (top row), CRT =50 ps (second row), CRT =140 ps (third row), and CRT =500 ps (bottom row)
