1. A method of generating a cross-sectional image of a surface within a tissue using an optical coherence tomography (OCT) system comprising: acquiring a plurality of OCT A-scans from within the tissue, at least some of the A-scans being orthogonally displaced from the surface to be imaged; generating a cross-sectional image of the surface within the tissue by compounding a plurality of A-scans, wherein at least a subset of the A-scans are selected from positions displaced orthogonally with respect to the surface, such that speckle in the cross-sectional image is reduced compared to a cross-sectional image generated only from A-scans along the surface; and displaying or storing the resulting cross-sectional image.
