Measuring Tissue Optical Properties by Optical Coherence Tomography
基于光学相干层析术的组织光学性质测量

Taking account of multiple scattering effects in the model of optical coherence tomography (OCT),an algorithm is developed to extract depth-resolved tissue optical properties including scattering coefficient and anisotropy factor.By adding absorption coefficient as the third fitting parameter in the algorithm,it is possible to reduce fitting errors introduced by sample absorption.With the adapted algorithm based on the extended OCT model,absorption coefficient can also be extracted.The validity of those algorithms is experimentally verified by measuring optical properties of solution of polyethylene spheres.
