Outline of Final Research Achievements

The aim of this research was to apply the technologies of augmented reality (AR) and three-dimensional (3D) printing to the field of interventional radiology for the improvement of the effectiveness and safety of interventional radiology procedures. We established a method of creating three-dimensional printing simulation models and evaluated them for simulation of interventional radiology procedures such as endovascular treatment. In addition, we developed an augmented reality system to project three-dimensional images reconstructed from radiological images such as computed tomography (CT) onto a monitor with three-dimensional printing models used for evaluation of the system. We are planning to continue to further improve the system.

Academic Significance and Societal Importance of the Research Achievements

画像下治療（Interventional Radiology）は、低侵襲な治療・手技ではあるが、他の選択肢との優位性を示すためには、有効性および安全性の向上が不可欠である。通常、画像ガイドに使用する画像は二次元であり、三次元プリンティングによるシミュレーションモデルや仮想現実システムにて、術前および術中において、三次元の情報を活用することにより、手技の有効性（治療成績）および安全性の向上につながると期待される。
