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 period of scans all being taken during a first time period; acquiring a second set of longitudinal scans at a second plurality of transverse locations across the sample, said second plurality of scans being larger than the first plurality and said second set of scans all being taken during a second time period longer than said first time period and wherein at least some of the second plurality of transverse locations are close 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 matched pairs, 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 matched pairs; and 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 said relative movement during the acquisition of the second set of scans.
