Matthew J Everett, Keith E O Hara: Method of motion correction in optical coherence tomography imaging. Carl Zeiss Meditec, Stallman & Pollock, April 29, 2008: US07365856 (46 worldwide citation)

An image data set acquired by an optical coherence tomography (OCT) system is corrected for effects due to motion of the sample. A first set of A-scans is acquired within a time short enough to avoid any significant motion of the sample. A second more extensive set of A-scans is acquired over an ove ...
