Outline of Final Research Achievements

To realize 3D transillumination imaging of macroscopic internal body structure, we integrated our principles to develop a new technique. Through optimization using Monte Carlo simulation, a measurement system was constructed. We analyzed the characteristics of the developed system, and necessary improvements were made. In the animal experiments, the feasibility of imaging the internal body structure with the safe near-infrared light without radio-active exposure was verified. The feasibility of functional imaging such as tissue oxygenation state was also verified.
