Outline of Final Research Achievements

For the automatic documentization of surgical operations, we worked on developing the algorithm for recognition the various elements from the video of surgical operation, such as anatomical structure, surgical instruments, operative motion, and events during surgery. As a result, this algorithm has not reached the accuracy as we expected to the documentation of surgical operation. The difficulty in improving accuracy due to differences in anatomical structure and plasticity of organs among cases is cited as a factor of incomplete algorithm. However, it achieved relatively high accuracy for automatic recognition of less plastic objects such as surgical instruments.

Academic Significance and Societal Importance of the Research Achievements

手術動画の自動認識アルゴリズムの開発において,動画より認識が容易な対象物と認識の困難な対象物の特徴を把握できたことはきわめて有用と考えられる.グラウンディング技術は現在多方面で発展が期待されている分野であり,外科領域を含む医療分野におけるグラウンディング技術の応用にとって重要な試金石となった.今後,精度の高い手術器具の自動認識を基に,手術動画の文章化のアプローチ法を検討することで,さらなる発展が期待できると考える.
