Semantic Imaging Ontology

Ontology

Ontology-compatible semantic layer for quantitative CT/DICOM interoperability and AI-readable imaging workflows.

Ontology pages describe semantic imaging concepts only and do not define clinical interpretation logic, disease classification or treatment pathways.

Canonical Ontology Resource

core.ttl

Canonical semantic ontology for RSIF-compatible imaging concepts.

GitHub Ontology

Public semantic ontology repository for quantitative imaging interoperability.

Core Semantic Concepts

CTStudy

CT/DICOM imaging study semantic entity.

ROI

Region of interest semantic measurement entity.

CTAttenuation

Quantitative CT attenuation semantic concept.

VertebralAttenuation

Structured vertebral attenuation semantic entity.

LiverAttenuation

Structured liver attenuation semantic entity.

RSIFObject

Machine-readable structured imaging representation.

HUValue

Semantic representation of Hounsfield Unit values.

StructuredExport

Semantic export object for AI-readable interoperability.

Ontology Semantic Scope

The ontology layer is intended for:

  • semantic interoperability;
  • machine-readable imaging concepts;
  • structured quantitative imaging semantics;
  • AI-readable semantic representation;
  • ontology-compatible interoperability workflows.
