Figure 4
(a) and (b) The wPRTF curves of different algorithms at doses of (a) 30.1 MGy and (b) 113 MGy as a function of the resolution 1/d. The value of the dashed line is 1/e, which serves as the criterion for the highest achieved resolution. (c) and (d) The natural logarithmic variance of different algorithms at (c) 30.1 MGy and (d) 113 MGy. |
