Abstract

We have developed a new four-wavelength optical imager to evaluate the oxygen supply in human skin for peripheral circulation. It measures the reflected light from human skin by a CCD and presents the maps of hemoglobin distribution. This paper describes the principle, system configuration and performance test for human foot during and after venous and arterial occlusion. The obtained images showed distinct local difference in skin oxygenation due to blood flow.
