Figure 2

Resolution versus noise plots for various reconstruction methods. Traditional approaches that do not model detector blur cannot achieve spatial resolutions below approximately 0.275 mm FWHM resolution, whereas approaches that include deblurring can achieve resolutions down to about 0.15 mm with increased noise. These limits are marked with gray vertical bands. The proposed approach provides the best noise-resolution tradeoffs for the finest resolution reconstructions. A zoomed region of this plot (dotted rectangle) is discussed in Figure 3.
