Integration Notes

Real-world integration guidance for engineers implementing this attribute in Mirth Connect, FHIR gateways, HL7 v2 bridges, and cloud DICOM services. Authoritative source data where available; reference examples and operational notes where they add value.

FHIR Mapping

No direct FHIR ImagingStudy mapping published for this attribute. Some tags map indirectly via the Patient, Endpoint, or ImagingSelection resources — Phase 2b will expand coverage to those.

HL7 v2 Equivalent

  • MSH-7 (of MPPS message, time portion) Message Date/Time site-dependent
    MPPS-N-CREATE

    Time portion of MPPS message timestamp. Date portion goes to (0040,0244).

    Source: common convention

Verify against IHE Radiology TF Vol 2 and your facility's interface specification before production use.

Cloud DICOM Support

  • AWS HealthImaging Queryable
  • Azure DICOM Queryable
  • Google Cloud Healthcare Queryable

Performed Procedure Step Start Time is a Series-level QIDO-RS matching key, typically combined with PerformedProcedureStepStartDate.

Per-vendor source URLs and verification date in src/content/dicom/cloud-support.json#_meta. Status taxonomy: required (mandated on Store), queryable (QIDO-RS matching key), preserved (stored as-is), promoted (AWS top-level metadata), unsupported (stripped/rejected).

Real-World Sample Values

No representative sample value available — this attribute isn't present in the de-identified pydicom fixture set. Add a fixture covering this attribute to expand coverage.

Mirth Connect Example

JavaScript transformer snippets for the most-queried tags will be added as coverage expands.

Common Operational Errors

Operational error patterns for the most-queried tags will be added as coverage expands.
