Axial Resolution
Axial resolution measurement showing the Point Spread Function (PSF) for seven of the 14 same-ring coincidence distributions acquired
Camera Sensitivity (Brain/Breast Mode vs. Whole-Body Mode)
Data acquired with a 21.5 cm uniform cylindrical phantom
Single Module Dead Time
Count rate of fully processed single-hit events (triangle markers), compared to triggers rate (square markers) from the same detector module. Straight lines are linear extrapolations from values at lower activity density. Camera set up in brain/breast configuration.
Noise Equivalent Sensitivity
Noise Equivalent Sensitivity (NES) measured in brain/breast mode and whole-body mode.
