Figure 22.
Reconstruction of three slices at z=20 mm, y=50 mm, and x=0 mm (from top to bottom) through the FORBILD head phantom for combined data truncation from one realization of Poisson noise (250 000 photons). In (a), (f), (k), the ground truth, in (b), (g), (l), the reconstruction without truncation correction, in (c), (h), (m), the reconstruction using the basic approach, in (d), (i), (n), the reconstruction using the kink approach, and in (e), (j), (o), the FDK reconstruction using the hybrid approach is shown. The window was set to [−30 HU;130 HU].
