OSEM reconstructed data (8 subsets, second iteration smoothed with Hann filter shown) from the 1060 ml breast + filled torso data, for each labeled orbit with an incomplete sampling scheme, with a 6.1:1:12 lesion:breast-and-torso:liver-and-heart radionuclide concentration ratio. (a) Solid line is drawn through the 9.5-mm lesion. Note the increased background contamination with TPB (white arrow) as compared to the other orbits which do not maintain the large detector polar tilts, thus limiting more direct views of the heart and liver. Even with these incompletely sampled orbits, and more realistic absolute radioactivities within the phantom, the centrally located 9.5-mm lesion is clearly visible. Dashed arrow in CPA points to cold lesion holder, which can also be seen with the other orbits (see, also, InvCLOVER) and in Fig. 8. (b) Views of the 8-mm lesion at different transaxial and sagittal locations than the larger lesion.
