Paper Abstract

We present a new data reduction algorithm to quantify absorption and reduced scattering coefficients of living tissues. The method requires source-detector separations larger than 2 cm and provides a simple, economic way to characterize tissue optical properties in the range of 600-900 nm and blood oxygenation. The results show that blood oxygenation in tissue can be quantified simply and accurately with this method for diffusing steady-state light, provided a suitable base-line calibration is available.
