Abstract[English]
An optical coherence tomography (OCT) scanning system for measuring ocular tissue characteristics of a patient's eye. The system includes an OCT scanner configured to implement a scanning sequence on the ocular tissue that scans the ocular tissue with an optical signal to obtain OCT data based on a reflected version of the optical signal. The system includes a computer with a processor configured to provide control signals to the OCT scanner to implement the scanning sequence, and to determine a rate of change of the phase or amplitude data associated with the scans. The system determines a growth constant of the reflected version of the optical signal based on the rate of change of the phase or amplitude data, and determines, based on the growth constant, a diffusion coefficient associated with the cornea. The system determines, based on the diffusion coefficient, a quantitative parameter of the cornea.[French]
L'invention concerne un système de balayage par tomographie à cohérence optique (OCT) pour mesurer des caractéristiques de tissu oculaire de l'œil d'un patient. Le système comprend un scanner OCT configuré pour mettre en œuvre une séquence de balayage sur le tissu oculaire qui balaie le tissu oculaire avec un signal optique pour obtenir des données OCT sur la base d'une version réfléchie du signal optique. Le système comprend un ordinateur avec un processeur configuré pour fournir des signaux de commande au scanner OCT pour mettre en œuvre la séquence de balayage, et pour déterminer un taux de changement des données de phase ou d'amplitude associées aux balayages. Le système détermine une constante de croissance de la version réfléchie du signal optique sur la base du taux de changement des données de phase ou d'amplitude, et détermine, sur la base de la constante de croissance, un coefficient de diffusion associé à la cornée. Le système détermine, sur la base du coefficient de diffusion, un paramètre quantitatif de la cornée.
