Abstract

The present invention defines a method of correcting for eye movement during optical coherence tomography imaging. The method includes imaging (by scanning) a fundus of an eye to obtain a fundus image (for example, using an SLO); scanning the fundus to obtain a plurality of tomographic images (for example, using OCT); determining, at predetermined intervals, an alignment of the tomographic images with respect to the fundus image, and, if it is determined that there is a misalignment, determining the number of tomographic images that have been scanned in the predetermined interval since the previous alignment determination; determining the offset by which the tomographic images are misaligned; applying the offset to the next tomographic image to be scanned and rescanning the determined number of tomographic images that were scanned during the interval between misalignment being determined and offset being applied.
