Standalone Overlay Storage Retired

About this SOP Class

A SOP (Service-Object Pair) Class pairs an Information Object Definition (IOD) with a DIMSE service. In practice it's what two DICOM nodes negotiate when they associate — "I want to send you Standalone Overlay Storage, are you willing to store it?"

This SOP Class is retired from the current DICOM Standard. Legacy systems may still use it for compatibility; new implementations should prefer the active replacement.

Working with Standalone Overlay Storage

Integrating a new SOP Class into a PACS, VNA, cloud imaging platform, or interoperability engine? Saga IT's medical imaging team runs these deployments end to end. For DIMSE ↔ DICOMweb bridging or legacy-modality onboarding, our Mirth Connect services handle the routing and transformation.
