Figure 3

Radial activity profiles of the largest sphere (70 mm) depending on reconstruction algorithm and SBR. Edge elevations (Gibbs artifacts) can be observed after reconstruction with PSF + TOF and PSF (not displayed) at SBR1 (A, D, G) and SBR2 (B, E, H). SBR3 (C, F, I) shows no considerable artifacts. The gray lines indicate the respective smoothing spline.
