Claim Text:
1. A non-transitory computer readable medium storing executable instructions comprising: a coarse segmentation component configured to determine, for each of a series of B-scan images, a set of constraint boundaries, based on natural contours within a region of tissue, from an optical coherence tomography (OCT) B-scan image and truncate all image area outside of the constraint boundaries to provide a truncated image; a fine segmentation component configured to determine, for each truncated image, a set of pathology boundaries within the truncated image representing a cross-section of the pathological feature by defining an undirected graph having vertices representing image pixels and edges between the vertices having respective weights defined from a set of at least one image characteristic and find an optimal segmentation for the defined graph; a mesh generation component configured to link the sets of pathology boundaries from adjacent images in the series of B-scan images to generate a polygonal mesh representing a volumetric reconstruction of the pathological feature; and a user interface configured to provide the polygonal mesh to an associated display.
