Comparison between average signal intensity (top), signal intensity drift (center) and RMS stability without (left) and with (right) the PET insert installed. The signal intensity seems to be influenced by changes in the PET insert cooling system (arrows), which also affects the drift of the system. However, the RMS stability of the measurements is not impacted by the presence of the PET insert.
