About this SOP Class Lookup
In DICOM networking, devices negotiate which types of data they can exchange using SOP Class UIDs (Service-Object Pair). Knowing the UID helps verify if a PACS, Viewer, or Modality supports a specific image type (e.g., Enhanced CT vs Standard CT).
Who this calculator is for
- PACS administrators, integration engineers, and imaging developers reading DICOM logs.
- People validating whether a sender and receiver support the same storage class.
- Learners studying the role of SOP Class UIDs in DICOM networking.
When to use it
- Use this lookup when a modality or gateway reports an unfamiliar SOP Class UID.
- Use it to confirm whether a workflow involves standard, enhanced, or structured-report objects.
- Use it while documenting interoperability issues during PACS or viewer integration.
How to use this calculator
- Paste the UID string (e.g., `1.2.840.10008...`).
- Or type a Modality name (e.g., `CT`, `MR`, `Ultrasound`).
- The tool identifies the DICOM Storage Class.
Key assumptions
- The lookup covers a practical curated subset of common SOP Class UIDs rather than the full DICOM standard.
- A name match here helps with identification, but actual interoperability still depends on negotiated presentation contexts and implementation details.
- This tool is meant for investigation and teaching, not for validating full conformance claims.

Key Features
- Instant Calculation
- Private & Secure
- Mobile Optimized
Tips & Best Practices
- All standard DICOM UIDs start with `1.2.840.10008`.
- Common issues arise when a sender tries to send an 'Enhanced' SOP class to a receiver that only supports the older 'Standard' class.
Glossary of Terms
- SOP Class
- The definition of an Information Object (image type) and the Service (storage, print, query) combined.
- UID
- Unique Identifier. A numeric string that uniquely identifies items in DICOM.
