Figure 3
(a) Simulated homogeneous circle: the background pixels are set to 0.0, the pixels inside the circle are set to 1.0. The image size is 512 × 512 pixels. The dashed red circle identifies the FOV for the interior tomography case. (b) FBP reconstruction of a sinogram with 800 views × 512 pixels in standard tomography. (c) FBP reconstruction of a sinogram with 800 views × 200 pixels in interior tomography with FOV depicted in (a). The image is zoomed to have the same dimensions as (a) and (b). (d) Comparison of the line profiles along the segment D, indicated in (a), for the reconstructions shown in (b) (blue line) and (c) (green line).
