Synthesised Longitudinal Images of the Retina of the Living Eye Generated Using Tansversal OCT Images Acquired at Different Depths

Abstract

Usually, when collecting longitudinal OCT slices (slices roughly perpendicular to the surface of the retina), an OCT has to be assisted by a scanning laser ophthalmoscope (SLO), a fundus camera or a simple CCD visualisation unit to guide the selection of the image to be taken. Quite often, the procedure has to be repeated several times to locate some features in the retina. With a system as described in this paper, once a collection of transversal (roughly parallel to the retina) OCT images is stored, a longitudinal image at any position can be synthesised.
