Abstract
Absorption and reduced scattering coefficients calculated from spatially resolved diffuse reflectance measurements are usually assumed to be unreliable for wavelengths lower than approximately 600 nm. A correction factor was developed for non-homogenous distribution of absorbers concentrated in discrete cylindrical blood vessels. The concept of an effective absorption coefficient extends the applicability of diffusion theory too much lower wavelength regions.
