1. A method for segmenting full-range images generated by an optical coherence tomography (OCT) system, said system having sample and reference arms and wherein the zero-delay position in the sample is defined as the position at which the optical path lengths of the sample and reference arms are equal, the method comprising: acquiring an OCT B-scan of a sample using an interferometer by collecting interfering light between signal light reflected from a sample and reference light, wherein the signal light is scanned transversely across said sample and wherein the sample extends to both sides of the zero-delay position, creating both real and complex conjugate images; segmenting at least one tissue surface in said OCT B-scan, wherein the tissue surface extends to both sides of the zero-delay position; and storing or displaying the segmented surface.
