Outline of Final Research Achievements

It is difficult to measure the 3D shape of organs by Time-of-Flight technology since the human tissue is the translucent and closed environment inside the human body causing multi-path reflections. We developed the new camera to eliminate the effect of the multi-path of light reflections and scattering of the light. We also proposed the 3D reconstruction method from the camera. We developed endoscopic surgery supporting system which visualizes the inside of the organs and tracks the visualization with the deformation of the organ shape. Moreover, we applied some proposed methods to real surgery and evaluate the effectiveness of helping it.

Academic Significance and Societal Importance of the Research Achievements

近年、患者の負担が少なく快復が早いことから内視鏡手術が注目されている．しかし、一般的な内視鏡で得られる情報はモニタに表示される視野の狭い2次元画像のみで腹腔へ挿入しているため視点の自由も限定的である。そのため術者に高度な技術を要求することから開腹手術と比べて効率や安全性が劣るという問題がある。本研究では、新たな光計測技術を開発し非接触でリアルタイムの臓器の計測・推定手法を開発した。また、これら基盤技術の一部を臨床応用に適用し、実証を行った。
