SOP Class Lookup accuracy and testing

This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.

Formula source

  • Uses the checked-in calculator function for dicom-sop-class-lookup.

Test cases

Default input regression check

Generated from the checked-in default inputs and calculate function.

Inputs

  • UID or Name:

Known limitations

  • This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
  • Use the result as a planning estimate unless the calculator page states a stricter purpose.

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.

Unit handling

  • UID or Name accepts text values.

Rounding rules

  • Number displays use up to 2 decimal places in the calculator UI.
