眼科光学相干断层扫描(Optical Coherence Tomography,OCT)是利用低相干光对视网膜组织进行断层成像的技术。在眼科领域,OCT是临床诊疗过程的重要工具,其核心优势是无创、高分辨、快速成像。2019年之前,中国眼科OCT市场长期由进口厂商主导,2019年起,国产厂商崭露头角,以视微、图湃为代表的厂商陆续获得了NMPA批准,国产替代的...
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。因此它能够...

Question How well does the Gemini Pro vision-language model (VLM) perform in expert-level diagnostic and management tasks for macular diseases using optical coherence tomography (OCT) scans? Findings In this cross-sectional study including 50 expert-labeled OCT scans, the VLM showed ...
Optical coherence tomography angiography (OCTA) is a relatively new imaging technique that provides more advanced photos of the retina. OCTA is derived from OCT technology. An OCTA scan provides just as much information as OCT, but with more advanced, three-dimensional images. ...
History Optical coherence tomography was first introduced commerically by Carl Zeiss in 1996. The first commerically available OCT was based on time-domain technology (TD). The Stratus TD-OCT (Carl Zeiss Meditec, USA) can scan resolutions up to 10 micron
