Abstract
An optical coherence tomography system is provided. The system includes an OCT imager; a two-dimensional transverse scanner coupled to the OCT imager, the two-dimensional transverse scanner receiving light from the light source and coupling reflected light from a sample into the OCT imager; a computer coupled to receive 3D OCT data from the OCT imager, the computer further processes the 3D OCT data; wherein the processing the 3D OCT data includes: correcting motion artifacts in baseline mode; generating reference data in baseline mode; performing segmentation to identify volumes of interest; extracting feature information, the feature information including reflectivity, texture, or the combination thereof.
