| Outline of Final Research Achievements |
In order to realize the visualization of the three-dimensional structure of blood vessels, we aimed to develop a three-dimensional imaging system for blood vessels using near-infrared light and a lens array, and established its basic elemental technology. We proposed a three-dimensional measurement method that reduces the influence of scattering by refocusing using the light field and angle filtering using the lens array. We confirmed the basic principle and examined the effectiveness by the prototype.

| Academic Significance and Societal Importance of the Research Achievements |
現在実用化されている静脈可視化装置は２次元情報の提示にとどまっており，平面および深さ方向の同時取得が行える装置は実現されていない．静脈の立体構造把握は，採血や点滴時の血管の探索に有用である．本研究をさらに発展させ，血管の探索がスムーズに行えるようになれば，採血や点滴に要する時間が短縮できやり直しも少なくできる．高齢化に伴う患者増加や人手不足が深刻な医療現場においては患者１人あたりに使える時間が非常に限られており，静脈穿刺に関する所要時間の短縮は医療の質の向上に役立つと考える．
