Figure 1.

Transverse (left) and sagittal (middle) views of the PET simulation setup in GATE for the dual-panel B-PET scanner design showing the reconstructed point sources without resolution modeling. Note the asymmetry along the y-axis getting stronger (darker peak away from kernel center denoted by dashed red lines) as we move away from the x-axis and closer to the detector panels. The numbered blue arrows indicate the four point sources for which the profiles are shown in figure 2. The axes on the right show the orientation of the detectors in physical space (with y pointing up towards the patient’s head and z in the direction away from the chest wall).
