Figure 13.

A quantitative evaluation of the reconstructed simulations of the bar pattern phantom (in figure 12) shows the relatively small effect of the 2D-ASG’s information loss compared to Poisson noise at 2mm grid pitch and septal thicknesses of 0.05, 0.1, 0.15, 0.2, and 0.25 mm at low, medium, and high resolutions. (a) RMSEs due to Poisson noise and 2D-ASG information loss w.r.t. the reconstructed images without grid and noise simulations. The error corresponding to images without noise represents 2D-ASG information loss effect. (b) Percentages of RMSEs increase due to Poisson noise w.r.t. 2D-ASG information loss.
