Abstract

Optical properties of biological tissue such as reduced scattering and absorption coefficients can be determined from the temporal or spatial reflectance curve of the diffusion process. Owing to its non-homogenous nature, the assumption of uniform optical parameters may not be valid in practice. We propose a new scheme to resolve the optical effective attenuation profile from the spatial reflectance curve of a non-homogeneous tissue. The algorithm reconstructs the linear attenuation profile along the line of measurement, rather than giving one single value for the coefficient for each reflectance curve. The technique was applied to the reconstruction of a 2-dimensional attenuation image.
