Fig. 6.

Phantom images from the first experiment reconstructed with Hybrid Recon (a coronal view, b sagittal view) and Flash 3D (c axial view) using 12 iterations and 16 subsets. Scaling was adjusted such the low background intensity is visible. The image reconstructed with Hybrid Recon shows hotspots in the centre between the kidneys (a, b) with similar intensity as the pancreas between the kidneys, as shown in b. In the Flash 3D reconstructed image, a higher intensity region is observed at the back of the phantom. Furthermore, in both images in the background, a low count rim around the kidneys can be observed
