DICOM Attribute
Recognizable Visual Features (0028,0302)
- Keyword
RecognizableVisualFeatures- VR
CS- VM
1
Definition
Indicates whether or not the image contains sufficiently recognizable visual features to allow the image or a reconstruction from a set of images to identify the Patient. If this Attribute is absent, then the image may or may not contain recognizable visual features. Enumerated Values: YES NO
From NEMA PS3.3 §C.7.6.1.
Attribute Metadata
This attribute is part of the current DICOM Standard. Its value representation is CS with multiplicity 1.

Value Representation
This attribute uses the CS
Value Representation. Multiplicity 1 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.
Cloud DICOM Support
AWS HealthImaging, Azure DICOM, and GCP Healthcare DICOM coverage rolls out by attribute. The QIDO-RS matching keys + Patient/Study/Series core (~50 attributes) are documented; lower-traffic attributes will be added as Saga teams encounter them in production.
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.
