The ability of NIR diffuse optical tomography in providing both anatomical and functional images

摘要

The experimental results of NIR optical tomographic imaging on human limbs are shown in this paper. The absolute absorption and scattering images roughly revealed the anatomical structure of the targets, where the bones were distinguished from the muscle. The images of the hemoglobin concentration changes calculated from differential image of absorption at two wavelengths showed the physiological phenomena during the forearm exercise.
