DICOM Standard Browser

A programmatic index of the NEMA DICOM standard. Every attribute, IOD, module, SOP class, VR, and transfer syntax — cross-linked, attributed, searchable. Integration notes for FHIR, HL7 v2, cloud DICOM, and Mirth Connect populate progressively from authoritative sources.

Looking up a DICOM tag?

Search all 5,213 attributes — type a tag ID, keyword, or name. Each hit lands on a page with FHIR mapping, HL7 v2 equivalent, cloud DICOM support, and real sample values.

Try: (0010,0010) Patient Name, (0008,0050) Accession Number
Integrating a specific modality?

Start with the object definition that your modality emits. Every CIOD lists its modules grouped by Information Entity (Patient / Study / Series / Image) with M / U / C usage flags straight from NEMA PS3.3.

Try: CT Image IOD, MR Image IOD, Ultrasound Multi-frame
Building a DICOMweb client?

Start with SOP Classes (what you'll negotiate over STOW-RS / QIDO-RS / WADO-RS) and Transfer Syntaxes (how pixel data is encoded on the wire). Each page carries AWS HealthImaging / Azure DICOM / GCP Healthcare support status.

Try: CT Image Storage, Explicit VR Little Endian

Popular Attributes

The tags engineers look up most — each carries Mirth Connect snippets, common-error scenarios, and full integration notes.

By Imaging Modality

CIODs grouped by acquisition context.

Radiology

CT, MR, X-Ray, Ultrasound, Nuclear Medicine, Mammography

Radiotherapy

RT Plan, RT Dose, RT Image, RT Structure Set, RT Beams

Cardiology

ECG, IVUS, Hemodynamic, Cardiac Electrophysiology

Pathology

Integration References

Cross-cutting browsing views over every DICOM attribute — FHIR paths, HL7 v2 segments, cloud vendor support, Mirth code, troubleshooting.

FHIR Mapping Reference

Every DICOM attribute that maps to a FHIR ImagingStudy element, grouped by FHIR path. Source: HL7 FHIR R5 StructureDefinition (CC0).
HL7 v2 Mapping Reference

Field-level DICOM ↔ HL7 v2 mappings grouped by segment (PID, OBR, ORC, PV1). Authoritative flag distinguishes IHE RAD-TF standards from facility conventions.
Cloud Support Matrix

AWS HealthImaging / Azure DICOM / GCP Healthcare per-attribute support status. Filterable, per-vendor source URLs pinned to _meta.
Mirth Connect Snippets

Production-adjacent JavaScript transformer patterns — DICOM-to-HL7v2, modality routing, UID de-dup, MPPS, character-set normalization. Reference material; validate before deploying.
Troubleshooting Reference

Common production patterns that break DICOM integration — grouped by severity, each with diagnosis + fix + tag link.
