Dual-channel whole-eye optical coherence tomography system and imaging method

Abstract

The invention discloses a dual-channel whole-eye OCT system, which includes a fundus OCT part, an anterior segment OCT part, a detection arm and a PC control platform; the light beam emitted by the near-infrared light source of the fundus part is output to the detection arm and the first reference through a fiber coupler. arm, the returned optical signal forms interference and then outputs to the first spectrometer; the light beam emitted by the near-infrared light source of the anterior segment is output to the detection arm and the second reference arm through the fiber coupler, and the returned optical signal forms interference and is output to the second spectrometer. The present invention also provides a method for performing whole-eye OCT by using the above-mentioned imaging system, in which the fundus tomographic image and the anterior segment tomographic image are post-processed through a PC control platform, thereby combining to obtain a whole-eye optical coherence tomographic image. The structure and method of the present invention are ingenious, so that the fundus part and the anterior segment part are imaged at the same time, and the OCT imaging of the whole eye is realized. The system structure is simple and compact, and the ophthalmic examination procedure and cost are greatly saved.

Description

technical field [0001] The present invention relates to a laser medical device and a laser imaging method, in particular to a laser ophthalmology examination device and a dual-channel all-eye optical coherence tomography method, specifically, a dual-channel all-eye optical coherence tomography that simultaneously realizes anterior segment and fundus imaging Coherent tomography imaging system and imaging method. Background technique [0002] During ophthalmological examination, the imaging examination of the anterior segment and fundus is very important. It is necessary to detect the anterior segment and fundus before various surgical treatments such as excimer laser surgery. In many patients with eye diseases such as diabetic retinopathy and macular It is also an indispensable item when checking for sex change, etc. In the past ten years, the research of Optical Coherence Tomography (OCT) has made important progress, especially in ophthalmology. widely used. However, curr...
