Abstract

Low-cost frequency domain photon migration instrument is used for neck-tumor analysis. Optical properties, absorption and scattering coefficients, are found at wavelengths 780 nm and 810 nm and accordingly hemoglobin concentration (in oxy- deoxy- and total forms), oxygen saturation, and blood volume fraction are calculated. We are able to identify normal and tumor regions in a human subject.
