| Outline of Final Research Achievements |
Computer-Aided Diagnosis (CAD) systems have gained attention as essential support for a clinical decision of “particular” diseases. The purpose of this study was to construct an integrating imaging diagnosis system focusing on a wide variety of diseases. This system combines the lesion detection by CAD with a diagnostic imaging ontology. uring this research period, three following ontologies were constructed: normal imaging anatomy, relations between diseases and image findings, and relations between image findings and image analysis. The integration of these three ontologies will not only be the foundation of a CAD that contributes to the detection of a wide variety of diseases but will be an explainable artificial intelligence.

本オントロジーは、画像データから得られる特徴量を抽出し、その出現パターンや濃度勾配等を既知の医学知見と照合し、医学的事象の判断能力の獲得を目指している。これは、人工知能技術による医療者の思考と類似した処理の実現である。本研究で構築したオントロジーは幅広い疾患に対応するCADシステムの基盤となるとともに、処理過程が明確となるため、説明可能な人工知能システムの開発にもつながると考えている。
