Abstract

Various methods are disclosed for mapping optical coherence tomography (OCT) data to facilitate review and diagnosis. In one aspect, high resolution 2D line scans are obtained along with lower density 3D cube scans and displayed in a manner to provide context to the clinician. In another aspect, OCT data is analyzed to provide information about non-uniformities of the tissue. Binary image maps of maps useful for determining tautness of membranes are also disclosed.
