Optical coherence tomography (OCT) is a micron-scale imaging method, analogous to ultrasound measuring the backreflection of infrared light rather than sound. It can operate in 2D and 3D mode and exceeds the fr
This richly illustrated, comprehensive guide will enable the reader to identify anatomy and ophthalmic disease as illustrated on optical coherence tomography (OCT). It is the most up-to-date atlas of OCT images, many of which have been obtained with the newer OCT technologies that offer excellent...
其中，光的相干长度和光源的中心波长是OCT系统的两个重要参数，它们决定了OCT系统的成像深度和分辨率。3. 光学相干层析成像的重要参数指标 OCT系统的重要参数指标主要包括成像深度、分辨率和敏感度。成像深度是指OCT系统可以成像的最大深度，它主要取决于光源的相干长度。分辨率是指OCT系统能够分辨出的最小细节，它主要取...

79Altmetric Metrics Abstract Optical coherence tomography (OCT) is a cross-sectional, micrometre-scale imaging modality with widespread clinical application. Typical OCT systems sacrifice lateral resolution to achieve long depths of focus for bulk tissue imaging, and therefore tend to have better axial ...
光学相干断层成像(Optical Coherence Tomography)是近年来发展起来的一项新的光扫描断层显像技术。它利用光纤干涉仪和近红外线光源,通过成像光纤导丝提供冠状动脉的二维横截面图像和三维重建图像。OCT技术最早应用于眼科相关检查,2001 年开始应用于冠状动脉成像。因为它具有超高的图像分辨率,可以达到10~15微米,比血管内超声(...
Optical coherence tomography angiography (OCTA) is widely used for non-invasive retinal vascular imaging, but the OCTA methods used to assess retinal perfusion vary. We evaluated the different methods used to assess retinal perfusion between OCTA studies
为了解决前面的那些缺陷,光学相干断层扫描(Optical coherence tomography, 后面简称为OCT)应运而生,它具有大视场组织检查,高分辨率检查,足够协助的穿透深度等特点,从左图来看,相比于其它成像技术,尽管OCT穿透深度相对较低,只有几毫米,但OCT与光学显微镜一样,在不接触组织的情况下,具有几微米及以下的高分辨率。因此它能...
From:Optical Coherence Tomography Technology and Applications:Second Edition 自此,OCT在临床上尤其是眼科领域,获得巨大发展。1993年,首次获得活体视网膜图像;1996年,首次报道动脉易损斑块OCT断层图像;此外在消化道、胆道、生殖道、尿道等均有离体成像试验报道。
