Title (EN) OPHTHALMIC OPTICAL COHERENCE TOMOGRAPHY (OCT) SYSTEM AND OPHTHALMIC OCT IMAGING METHOD
(FR) SYSTÈME OPHTALMIQUE DE TOMOGRAPHIE À COHÉRENCE OPTIQUE (OCT) ET PROCÉDÉ D'IMAGERIE OPHTALMIQUE OCT
(ZH) 一种眼科OCT系统和眼科OCT成像方法
Abstract:
(EN) An ophthalmic optical coherence tomography (OCT) system includes an OCT imaging system for a posterior segment of an eye and an OCT imaging system for an anterior segment of an eye. The OCT imaging system for the posterior segment of the eye includes a light path conversion device, and the OCT imaging system for the anterior segment of the eye includes a probe imaging device for the anterior segment of the eye. The probe imaging device for the anterior segment of the eye includes an ophthalmoscope, a first dichroscope and a first lens. When the ophthalmic OCT system is scanning image for the anterior segment of the eye, and after the light path conversion instruction is received by the light path conversion device, the signal light sent from the light source through the collimating mirror and scanning device respectively is converted into the probe imaging device for the anterior segment of the eye; the probe imaging device for the anterior segment of the eye drives the first dichroscope to cause the signal light to be reflected into the ophthalmoscope so as to carry out the scan imaging for the anterior segment of the eye. An ophthalmic OCT imaging method is used to image the anterior segment of the eye, which can both remain the point of fixation clear during dioptric compensation and not influence the OCT imaging quality for the anterior segment of the eye.
(FR) L'invention concerne un système ophtalmique de tomographie à cohérence optique (OCT) comprenant un système d'imagerie OCT pour un segment postérieur d'un œil et un système d'imagerie OCT pour un segment antérieur d'un œil. Le système d'imagerie OCT pour le segment postérieur de l'œil comprend un dispositif de conversion de trajet de lumière et le système d'imagerie OCT pour le segment antérieur de l'œil comprend un dispositif d'imagerie de sonde pour le segment antérieur de l'œil. Le dispositif d'imagerie de sonde pour le segment antérieur de l'œil comprend un ophtalmoscope, un premier dichroscope et une première lentille. Lorsque le système ophtalmique OCT balaie une image pour le segment antérieur de l'œil et après que l'instruction de conversion de trajet de lumière est reçue par le dispositif de conversion de trajet de lumière, le signal lumineux envoyé par la source lumineuse à travers le miroir collimateur et le dispositif de balayage, respectivement, est converti dans le dispositif d'imagerie de sonde pour le segment antérieur de l'œil; le dispositif d'imagerie de sonde pour le segment antérieur de l'œil commande le premier dichroscope pour qu'il amène le signal lumineux à êre réfléchi dans l'ophtalmoscope de façon à mettre en œuvre l'imagerie par balayage pour le segment antérieur de l'œil. Un procédé d'imagerie ophtalmique OCT est utilisé pour imager le segment antérieur de l'œil qui peut à la fois rester le point de fixation clair au cours de la compensation dioptrique et ne pas influencer la qualité de l'imagerie OCT pour le segment antérieur de l'œil.
