Revolutionizing Heritage Science with AI-Powered DICOM Integration
The DICOCH Pipeline: Unlocking Conservation-Grade Reproducibility and Global Digital Reuse for Cultural Heritage NDE Data.
Executive Impact: Transforming Cultural Heritage Preservation
The DICOCH pipeline addresses critical limitations in cultural heritage imaging, ensuring conservation-grade reproducibility and seamless digital reuse. By standardizing NDE data, institutions can achieve unparalleled accuracy, interoperability, and long-term preservation for invaluable artifacts.

The DICOCH pipeline is built on four core principles:
- Standards Compliance: Adhering to DICOM IOD, VR, and VM rules, aiming for 'errors=0' validation.
- Independence: Maintaining standard public tags while using Private Groups for heritage-specific info.
- Web Interoperability: Embedding stable URIs for IIIF Presentation 3.0 Manifests.
- Reproducibility: Ensuring an auditable trail with packaged transformation parameters and private dictionary definitions.
The DICOCH workflow is a Generation-Validation-Publication (GVP) process:
- Generation: Python pydicom-based conversion of raw images and Excel metadata into DICOM Part 10 files. Includes SOP Class selection, UID generation, and automated pixel/display settings.
- Validation: Strict compliance checks using dciodvfy, with private dictionary injection for recognizing custom tags.
- Publication: Generation of 8-bit JPEG derivatives and IIIF Presentation 3.0 Manifests for web deployment.
The DICOCH Private Data Dictionary (Group 0013,xxxx, Private Creator NRICH_DICOCH) extends DICOM for cultural heritage contexts. It includes:
- Heritage Context: Provenance, material, cultural property numbers.
- Rights and Policy: Copyright holder, usage license, access tiers.
- Technical Extension: IIIF linkage parameters, material calibration.
This ensures machine-readability and strict validation.

| Scope/object of description | Patient-Study-Series centred | Equipment-process-defect centred | Object/collection centred with provenance, period, material, condition |
| Data objects/modalities | CR/CT/MR/US, etc. | industrial formats for inspections | CR/CT plus ROI statistics and IIIF derivatives |
| Semantic metadata | Focused on patient demographics and medical history | Focused on manufacturing parameters and flaw reporting | DICOM-compatible; Private Group (0013,xxxx) for context, ROI/HU, IIIF, rights |
| Measurement and HU calibration | Clinical HU (Rescale); viewer tools | Thickness/defect metrics for decisions | HU monotonicity preserved; records Nominal HU via HUCalibrationSequence |
| Validation/reproducibility | IOD + VR/VM conformance; vendor interoperability | Profile-driven documentation | Verification-first automation: generate → dciodvfy → IIIF (Errors=0 threshold) |
| Governance/dictionary | DICOM WG; PS3.x | ASTM/industrial guides | Fixed Private Creator NRICH_DICOCH; public dictionary + exemplars |

Case Study: Andong Hahoe Mask (National Treasure No. 121)
The DICOCH pipeline was validated using the Andong Hahoe Mask, an artifact from the Goryeo Dynasty. This object, carved from alder wood, presented unique challenges due to its low-attenuation organic material and complex geometry.
The pipeline successfully generated valid DICOM CR and CT Image Storage instances. It correctly encoded volumetric geometry and applied a baseline medical transform (m=1, b=-1024) for HU standardization, ensuring compatibility with standard medical viewers.
Quantitative analysis revealed consistent high-density values across lacquer layers and wood core, and accurate capture of metal fastener properties, demonstrating the pipeline's ability to handle diverse heritage materials.
