CT-Focused Ontology Framework Enables More Meaningful Radiation Dose Aggregation

A new Operational Ontology for Radiology (OOR) framework (34 classes, 15 object properties, 156 data properties) models CT workflow, enabling more clinically relevant radiation dose aggregation.

• The OOR addresses gaps like lack of semantic clinical context and inconsistent procedure definitions by modeling the entire radiology workflow from ordering to interpretation.
• A CT-focused implementation comprises 34 classes, 15 object properties, and 156 data properties.
• In a demonstrative use case, OOR enabled more clinically relevant radiation dose aggregates from clinical CT data.
