Title (EN) SCANNING AND PROCESSING USING OPTICAL COHERENCE TOMOGRAPHY
(FR) BALAYAGE ET TRAITEMENT UTILISANT LA TOMOGRAPHIE À COHÉRENCE OPTIQUE
Abstract:
(EN) In accordance with some embodiments, a method of eye examination includes acquiring OCT data with a scan pattern centered on an eye cornea that includes n radial scans repeated r times, c circular scans repeated r times, and n* raster scans where the scan pattern is repeated m times, where each scan includes a A-scans, and where n is an integer that is 0 or greater, r is an integer that is 1 or greater, c is an integer that is 0 or greater, n* is an integer that is 0 or greater, m is an integer that is 1 or greater, and a is an integer greater than 1, the values of n, r, c, n*, and m being chosen to provide OCT data for a target measurement, and processing the OCT data to obtain the target measurement.
(FR) Selon certains modes de réalisation, la présente invention concerne un procédé d'examen oculaire qui consiste à acquérir des données OCT (tomographie à cohérence optique) avec un modèle de balayage centré sur la cornée d'un œil. Le procédé comprend n balayages radiaux répétés r fois, c balayages circulaires répétés r fois et n* balayages ligne par ligne où le modèle de balayage est répété m fois, chaque balayage comprenant des balayages A, n étant un entier supérieur ou égal à 0, r étant un entier supérieur ou égal à 1, c étant un entier supérieur ou égal à 0, n* étant un entier supérieur ou égal à 0, m étant un entier supérieur ou égal à 1 et a étant un entier supérieur ou égal à 1, les valeurs de n, r, c, n* et m étant choisies pour fournir des données OCT pour une mesure de cible ; le procédé consiste également à traiter les données OCT pour obtenir la mesure cible.
