Outline of Final Research Achievements

To realize 3D transillumination imaging of internal body structure and physiological function, we integrated our principles to establish a new technique, and developed a test system. Through this study, we achieved the following results.
(1) An inverse scattering problem was solved to obtain internal structure in a turbid medium using scattered light from the medium. (2) Blurred transillumination image could be improved by the deconvolution with a point spread function. (3) The problem of image blur was resolved using the convolutional neural network obtained by deep learning. (4) The feasibility of 3D transillumination imaging was confirmed using a tissue-simulated model phantom. (5) A test system was designed and manufactured. (6) The feasibility of functional imaging was confirmed in the identification of vein and artery in a transillumination image. (7) 3D functional transillumination imaging was achieved in animal experiments.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果は、次の意義を有する。(1)拡散性散乱体の内部構造の高分解能な透視像を世界に示し、学術的な新原理およびそれを実現する新手法の大きなポテンシャルを明確に実証した。(2)体内機能的変化の3次元光透視が実現された意義は大きい。提案手法は、放射線被曝がなく比較的小規模な装置にできることから、ベッドサイドでの使用も可能であり、臨床における実用性が高い。さらに、頭部等に対し造影剤なしの血管網撮影も可能となる。(3)これまで空間分解能の低さから普及してこなかった乳房や新生児頭部の光透視イメージングに、新たなブレークスルーが期待できる。
