Paper Abstract

A tissue discrimination algorithm of polarization sensitive optical coherence tomography (PS-OCT) based on optical properties of tissue was developed. We calculated three dimensional (3D) feature vector (intensity, extinction coefficient, birefringence) obtained by PS-OCT. The tissue types of each pixel were discriminated according to positions of the feature vectors in 3D feature space. This algorithm was applied for discrimination of human anterior eye chamber. Conjunctiva, selera, trabecular meshwork (TM), cornea and uvea were well separated in the 3D feature space and discriminated in good contrast.
