| Outline of Final Research Achievements |
To directly visualize pre-neurosurgical images, 3D images are to be produced and projected onto patient heads with the aid of Kinect V2 sensor. Projection onto four sides of two 3D-printed full-sized phantom heads led to the accuracy of 2.2±1.1mm by applying some specific computational processes. Projection under limited environment with patient hair or intubation tube, which is used during intraoperative anesthesia, provided the accuracy of 1.94±0.37 mm. To thoroughly exclude the effect of patient hair, 3D images were also visualized in the smart glasses. Information of patient head position using optical markers was acquired by motion capture cameras, and mechanical accuracy was 3.1±1.9mm. Application to two clinical cases disclosed the accuracy of 2.1±1.1mm.

| Academic Significance and Societal Importance of the Research Achievements |
脳神経外科手術前の画像をコンピュータディスプレーではなく直接的に頭皮上で可視化するプロジェクションマッピングの有用性と限界を明らかにした。また、副次的にスマートグラス（メガネ型ウェアラブル端末）への描出の方法論も見出すことができた。これら拡張現実の方法論が確立しその有用性が証明されれば多くの脳神経外科手術の安全性を高めることが期待される。
