Outline of Final Research Achievements

Given the leading role that blood flow plays in the transfer of body heat, we focused on the heat transfer efficiency of skin tissue, and developed a device for evaluating the blood perfusion. Heating in the local area of the skin surface, the skin-surface temperature response depends on the amount of blood perfusion. We estimated the skin blood perfusion by solving the bio-heat transfer equation with skin-surface temperature responses. In this study, we confirmed the ability of our new device to evaluate skin blood perfusion. However, we found no relationship between the ratio of the change of the estimated blood perfusion and the flowmeter value. We recognized that there are some research tasks to test the validity of the evaluations with our new device for Ischemia. The validity of evaluating skin blood perfusion must also be investigated in further study.
