Abstract

Determining optical properties of brain tissue is important for application of light in clinical diagnosis, surgery, and therapeutic procedure in brain disorders. Diffuse reflectance spectroscopy (DRS) is one of most promising technique for evaluating cortical hemodynamics [1] and assessment of tissue viability [2]. In this study, we investigate a method to estimate the spectral images of reduced scattering coefficients μ_s’(λ) and the absorption coefficients μ_a (λ) of in vivo exposed brain tissues in the range from visible to near-infrared wavelength (500-760 nm) based on DRS using a digital RGB camera.
