Figure 11
The reconstruction of the 601th synthetic sinogram (area [273:848, 273:848] of [1:1280,1:1280], pixel-value [0:0.5]). (A) From the original dataset without noise and 3601 projections. (B) From the original dataset with noise and 181 projections. (C) Using UDNN-128 for upscaling (181 projections). (D) Using the Bertram's directional interpolation (181 projections). (E) Using cubic interpolation (181 projections). (F) From the original dataset with noise and 91 projections. Region of interest shown zoomed in Fig. 12
