1. A method of detecting a stent in a lumen of a blood vessel comprising: generating an optical coherence image data set in response to an optical coherence tomography (OCT) scan of the blood vessel, the optical coherence image data set comprising a plurality of scan lines; storing the optical coherence image data set in a memory device; and identifying at least one stent strut of the stent by detecting, using a processor, a one-dimensional local cue in one or more scan lines of the optical coherence image data set and displaying a cross-sectional image of the blood vessel and one or more identified stent struts.
