Used in 5 Modules

This attribute uses the DS Value Representation. Multiplicity 1-n governs how many values may be encoded.

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

No standard HL7 v2 equivalent published for this attribute. Imaging-only attributes (Image Pixel data, technical acquisition parameters, modality-specific values) typically have no HL7 v2 carrier.

Extracted from pydicom test fixtures (MIT, de-identified).

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.
