Abstract :
Summary form only given.Biomedical imaging with diffuse light is a flexible noninvasive technique, which allows one to obtain the spatial distribution of the optical absorption and diffusion coefficients inside an object from intensity measurements with multiple sources and detectors. In many instances, the variations in absorption and diffusion coefficients can be associated with certain pathological changes, which provides a basis for a new efficient diagnostic method. One of the advantages of diffusion tomography is that it does not require the use of potentially harmful short-wavelength radiation, since the diffusive regime of light propagation in typical human tissues is a fairly good approximation in the visible spectral range.
