| Outline of Final Research Achievements |
We have developped navigation systems using augmented reality (AR) on smartphones and headmounted displaies for interventional radiology procedures. 3D images reconstructed from CT images or a virtual protractor which is prepared in advance are displayed on the body surface by using various registration methods. Accurate needle puncture becomes possible by using these navigation systems.

| Academic Significance and Societal Importance of the Research Achievements |
体内に針を刺して行う検査や治療は、従来は超音波やCT等の画像ガイド下に行われていたが、主に二次元の画像情報を用いていた。本研究にて、CT画像から作成した三次元画像や、予め用意した仮想分度器を拡張現実（AR）として、種々の位置合わせ法を用いて患者体表に重ね合わせることで、あたかも三次元の構造がそこに存在するかの如く表示可能となった。これにより、従来のナビゲーションに加え、新たな三次元情報を参照しながら穿刺できるため、不慣れな術者でも正確に針を穿刺することが期待される。
