PROBLEM TO BE SOLVED: To provide new processing techniques for optical coherence tomography (OCT) data that allow for use of full-range OCT images and improved visualization of the image.SOLUTION: These techniques minimize the central line artifact and the complex conjugate artifact without requiring additional system hardware or significantly increasing post-processing time. The central line artifact is minimized by normalizing each A-scan to account for ripples at the zero-delay position. The complex conjugate artifact is minimized by segmentation of a layer or layers that cross the zero-delay position, and in some embodiments by further segmentation of other surfaces based on the segmentation of the initial layer or layers. The segmentation information is then used to selectively attenuate the complex conjugate image. It may also be used for other purposes, such as dewarping.SELECTED DRAWING: Figure 3
