Abstract

The feasibility of imaging the physiological functions by laser transillumination is studied. Using a near-infrared light, the transillumination images of a mouse abdomen and a rat brain were obtained. The physiological changes such as local hypoxia could be visualized in each of the transillumination images. It was found that the changes in the blood volume and in the oxygenation state could be detected using multiple wavelengths of light. In this way, the spatial distributions of these changes could be visualized in the transillumination images noninvasively.
