Figure 13
Reconstructions of linear attenuation coefficients (in cm−1) for two phantom slice ROIs. The first row shows a ROI marked in cyan in Fig. 12, reconstructed from (a) 1600 projections, (b) the same number of projections as in (a) but with 16 times shorter t, (c) the same t as in (a) but 16 times less N. The second row shows a ROI further away from the rotation axis marked in magenta in Fig. 12 with the same t and N settings as in the first row. |
