Figure 18
The selected area marked by the red window in Fig. 17(A)[link] enlarged (area [651:951, 701:1001] of [1:2560,1:2560], pixel-value [−1/2560:1/2560]). (A) From the original dataset with 3601 projections. (B) From the original dataset with 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 91 projections. Similar to Fig. 9[link], in the proposed method (panel C) the level of noise is lower compared with the other methods and there are fewer rotational artefacts.
