Outline of Final Research Achievements

The purpose of our research project is to construct support system for Minially Invasive Surgery (MIS) using Real-time Finite Element Method and the information about a target organ acquired during surgeries. We studied the fundamental techniques of the support system: 1) a real-time finite element method for estimating the deformation of the target organ by deep neural networks;
2) a method for detecting surgical instruments from endoscopic images.

Academic Significance and Societal Importance of the Research Achievements

本研究では,実時間有限要素解析システムと術中組織変形情報を組み合わせ,患者の状態に応じた適切な初期条件を設定し,その条件下での組織の振舞いを実時間で且つ非線形FEMと同等の解析精度で推定する,独創的な手法を開発する.これにより, 他の研究機関と比べても突出した精度で,人体組織の見えと動きを再現する患者指向組織モデルと,それを用いた手術計画や手術シミュレーションなどの次世代の低侵襲手術支援システムが構築できる.このシステムにより,医師は術中の視野を容易に想像でき,術中と同様の判断や手術手技の訓練を術前に行え,低侵襲手術の安全・正確性の飛躍的な向上に寄与できる.
