Figure 14
Reconstructions computed by GRID-E (a), ADMP-E (b) and ADMP-V (c) of the SL sinogram with 200 views × 512 pixels, additional Poisson noise with = 2.5% of the sinogram mean and ZIF = 4. The green segment in (a) shows the position of the line profiles displayed in Fig. 15(a). (a) SL phantom. (b) GRID-E reconstruction. (c) ADMP-E reconstruction. (d) ADMP-V reconstruction. |
