No data at hand? digital IEC phantom, NU 2-2012 fill, lung insert, 3 replicates (4.4 MB): downloaded from the project website and analysed automatically
For security reasons a browser cannot open a typed path: click Select DICOM folder and navigate to the study folder (the exported study folder). The folder may contain the PET replicates and the CT; sub-folders are read too. Supported: uncompressed DICOM (Explicit/Implicit VR), also inside .zip files.

All six spheres (10-37 mm) hot at the sphere:background ratio; lung-residual slices within 30 mm of the lung-insert ends are excluded.
true activity-concentration ratio of the fill (nominal 4:1; enter the measured value if known)
Profiles identify the system and provide published reference values for comparison (never PASS/FAIL).

Take the limits from the manufacturer's documentation or your acceptance protocol. Contrast limits refer to the sphere types of the edition chosen for the limits (NU 2-2012: 28/37 mm cold; NU 2-2018 or any: all hot).
used only for the expected activity concentration
empty = standard: 10 mm (NU 2-2012), 30 mm (NU 2-2018)
A baseline is your own earlier result (e.g. acceptance test). Create one with "Save as baseline" after an analysis.
