| Outline of Final Research Achievements |
In this study, we aimed to develop a technique for grasping blood dynamics easily and quantitatively in a non-contact manner using spatially-resolved near-infrared spectroscopy with a new sensor arrangement, and explored conditions and methods that can be measured accurately. Based on the computer simulation of light propagation, the change in measurement depth and the change in sensitivity due to the combination of distances between transmitters and receivers were quantitatively clarified. From these results, we have established the basis of a new measurement method that can make the measurement depth variable. In addition, the developed oximeter could be shown to be useful for vascular surgery.
