Claim One:
1. A method for correcting the coordinates of longitudinal optical scattering profiles obtained from within a sample by an optical coherence tomography (OCT) imager, wherein the correction compensates for relative movement between the OCT system and the sample, said method comprising the steps of: acquiring a first set of longitudinal scans at a first plurality of transverse locations within the sample, said first set of scans all being taken during a period short enough so that said relative movement is less than the amount that would cause objectionable image distortion; acquiring a second set of longitudinal scans at a second plurality of transverse locations in a two dimensional pattern within the sample, said second plurality of scans being larger than the first plurality and wherein at least some of the second plurality of transverse locations on the sample correspond substantially to at least some of the first plurality of transverse locations on the sample; matching certain ones of said second plurality of scans to certain ones of said first plurality of scans to define pairs of scans, said matching being based on an evaluation of whether the associated optical scattering profiles of the scans are substantially similar; determining a displacement between coordinates associated with each of said pairs of matched scans; adjusting the coordinates associated with at least some of the scans of the second set based on the determined displacements thereby correcting for inaccuracies created by relative movement during the acquisition of the second set of scans; generating an image using the second set of scans and the adjusted coordinates; and displaying the image.
