The system can identify relevant series during the storing process and mark the series as SIG images.
You can define criteria to prompt the system to mark SIG images automatically.
Some examples of the criteria include:
A volumetric series with a small number of thick images.
A series with a certain type of derived/secondary images.
All the series in the study excluding the large volumetric series images. The study includes all non-volumetric series plus compressed volumetric series.
A series with specific terms in the series description.
A SIG that was defined in the modality based on a certain DICOM tag.
