| Outline of Final Research Achievements |
Virtual reality (VR) in the field of medicine attracts attention as a new medical imaging, which is converted from computed tomography (CT) and magnetic resonance imaging (MRI) and also used for preoperative surgical simulation in Japan. In this study, various pathological movements observed in respiratory and circulatory organs were mainly researched whether or not VR can provide deep recognition for the patho-physiological movements in human body. As a results, various paradoxical/abnormal movements were found in patients with chronic obstructive pulmonary disease, lung cancer (occluded main bronchus by cancer), and aortic valve stenosis (after Transcatheter Aortic Valve Implantation: TAVI).

| Academic Significance and Societal Importance of the Research Achievements |
ヴァーチャル・リアリティ（VR）は、人工環境・サイバースペースをあたかも現実のものとして人に知覚させる技術である。「人類の認知を拡張する」映像技術と言われ、いち早くゲーム業界で実用化され、医学教育や医療への応用が進んでいる。今回は医学・医療用VRソフトウェアを用いて、4次元で撮影されたCTやMRI（心臓、肺）をVRに変換して種々の疾患の観察を行った。結果として、肺や心臓の様々な疾患で「健常者には見られない異常な運動」が生じていることをVRで容易に認識できることが確認され、患者説明や医療者の病態の理解に有用であろうと思われた。
