Slices from reconstructed images of the same rat scanned in microPET P4, once in a) single mode, and once in b) dual mode. A line was drawn through identical structures in both scans to obtain scaled line profiles. The line profile from the single scan (a) shows sharper peaks compared to the profiles from the dual scan (b). This is consistent with our expectation that image resolution is compromised in the dual scan, where the brain is positioned away from the CFOV.
