| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In autotransplantation, surgeon subjectively judges if the organ to be transplanted is healthy from the color. However it is difficult to discriminate a small difference of organ’s color by visual inspection. In this paper, we focus on the tissue oxygen saturation (StO2) that represents balance of oxygen demand and supply in tissue for the quantitative evaluation of blood circulation and try to estimate its value by transmission light intensity analysis. We developed a system for measurement of transmission light intensity using a compact spectrometer and a halogen light source and collected transmission light intensity data from pig’s small intestines using this system. Absorbance of the tissue was then calculated from those data. On the basis of Beer-Lambert law, we estimated StO2 from the calculated absorbance. Results of evaluation experiment of blood circulation state in pig's small intestine suggested the possibility of quantitative evaluation of tissue viability by the proposed method. | |
