DICOM PS3 Series (NEMA / ISO 12052)
Digital Imaging and Communications in Medicine (DICOM)
DICOM (Digital Imaging and Communications in Medicine) is the global standard for capturing, storing, transmitting, and viewing medical images across modalities (CT, MRI, PET, Ultrasound, X-Ray) and Picture Archiving and Communication Systems (PACS). It standardizes image data structures, rich clinical metadata headers, transfer syntaxes, and network protocols (C-STORE, C-FIND, C-MOVE, DICOMweb RESTful WADO-RS/STOW-RS).
Scope & Applicability
Applies to medical imaging modalities, PACS archives, diagnostic workstations, radiation therapy equipment, and cloud medical image analysis platforms.
Non-Coverage Boundaries
Does not define general clinical narrative documents (which use HL7 CDA/FHIR) or non-imaging electronic health records.
Key Clauses & Control Requirements
DICOM Service Class Specifications (DIMSE & DICOMweb)
Core operations: Storage (C-STORE), Query/Retrieve (C-FIND, C-MOVE, C-GET), and web RESTful endpoints (WADO-RS, STOW-RS, QIDO-RS).
Media Storage and File Format for Media Interchange
Standard file structure: 128-byte preamble, 'DICM' 4-byte prefix, and dataset tags with explicit/implicit Value Representations (VR).
Required Regulatory & Audit Evidence Artifacts
- [✓]Vendor DICOM Conformance Statement (DCS) detailing supported SOP Classes and Transfer Syntaxes
- [✓]Network DICOM association negotiation and transfer logs
- [✓]De-identification / Anonymization Profile validation test reports for clinical trials
“DICOM is not just a JPEG with metadata. It is a strict stateful network association protocol and clinical metadata schema. Dropped associations during large multi-slice transfers require resilient queue and retry architectures.”

Frequently Asked Questions
What is a DICOM Conformance Statement (DCS)?
A formal technical document published by a vendor specifying exactly which DICOM Service Classes, Information Objects, and Transfer Syntaxes their software supports.
