Figure 9.

Transversal slices through the reconstructed hot-rod phantom. The voxel pitch is 0.25 mm, and the slice thickness is 20 mm. The complete datasets of trig 1 and trig 3 (all) are truncated for comparison: trig 3 all matches trig 1 decays in terms of the number of tracer decays and trig 3 counts matches trig 1 all in terms of the number of coincidences (table 3). The third column shows the absolute difference multiplied by a factor of 5 between the two reconstructions for each measurement.
