Outline of Final Research Achievements

We have developed an experimental model for noninvasive multi-imaging system that is composed of micro X-movie imaging and near infrared spectroscopic imaging (NIR-imaging). By using the NIR-imaging with 940 nm reflected LED light, the femoral artery and vein can be visualized as distinguished each other on the base that the optical absorption is expressed by the relative amount of oxy-hemoglobin verses deoxy-hemoglobin. The combined use of NIR-imaging and X-movie imaging will be of great value and convenience for acute diagnosis in emergency medicine.
