| Acronyme | RO |
| Description | The Radiomics Ontology aims to cover the radiomics feature domain with a strong focus on first order, shape, textural radiomics features. In addition, in the original version. it includes classes about segmentation algorithms and imaging filters.<br>Due to a recent collaboration with the IBSI (International Biomarkers Standardization Initiative), the ontology has been expanded (v 1.6) and it includes all the entities presented in the IBSI document. Therefore, a broad coverage of not only radiomics features, but also every entity (e.g. software properties, filter properties, features extraction parameters) involved into radiomics computation has been added. In the latest version (v2.0), the ontology URIs have been updated to reflect the codes avaialble in the IBSI latest manual |
