The 1002th real-world sinogram with only the intermediate row/projections (rows 21, 61,…, 3581, pixel-value [0.59:0.74]). (A) From the original dataset. (B) Prediction for these rows using UDNN-128 for upscaling. (C) Prediction for these rows using Bertram's directional interpolation. (D) Prediction for these rows using cubic interpolation. Each image ratio is different from the original for presentation purposes. Region of interest is shown zoomed in Fig. 14. |
