We demonstrate and compare two image processing methods for visualization and analysis of three-dimensional optical coherence tomography (OCT) data acquired in eyes with different retinal pathologies. A method of retinal layer segmentation based on a multiple intensity thresholding algorithm was implemented in order to generate simultaneously outer retinal topography maps and reflectivity maps. We compare the applicability of the two methods to the diagnosis of retinal diseases and their progression. The data presented in this contribution were acquired with a high speed (25,000 A-scans/s), high resolution (4.5 microm) spectral OCT prototype instrument operating in the ophthalmology clinic.
我们展示并比较了两种图像处理方法,用于可视化和分析在患有不同视网膜病变的眼睛中获取的三维光学相干断层扫描(OCT)数据。为了同时生成视网膜外层地形图和反射率图,实施了一种基于多强度阈值算法的视网膜层分割方法。我们比较了这两种方法在视网膜疾病诊断及其进展方面的适用性。本论文中呈现的数据是使用一台在眼科诊所运行的高速(25,000次A扫描/秒)、高分辨率(4.5微米)光谱OCT原型仪器采集的。
