A technique to generate large field of view projection maps of arbitrary optical coherence tomography (OCT) data is described. The technique is divided into two stages - an image acquisition stage that features a simple to use fast and robust retinal tracker to get motion free retinal OCT volume scans - and a stitching stage where OCT data from different retinal locations is first registered against a reference image using a custom pyramid-based approach and finally stitched together into one seamless large field of view (FOV) image. The method is applied to data recorded with a polarization sensitive OCT instrument in healthy subjects and glaucoma patients. The tracking and stitching accuracies are quantified, and finally, large FOV images of retinal nerve fiber layer retardation that contain the arcuate nerve fiber bundles from the optic nerve head to the raphe are demonstrated.

从内部采集运动补偿体积光学相干断层扫描数据生成大视场正面投影图像

描述了一种生成任意光学相干断层扫描（OCT）数据的大视场投影图的技术。该技术分为两个阶段 - 图像采集阶段，具有简单易用、快速且强大的视网膜跟踪器，以获得无运动的视网膜 OCT 体积扫描 - 以及拼接阶段，首先将来自不同视网膜位置的 OCT 数据与参考图像进行配准使用基于金字塔的自定义方法，最终拼接成一个无缝的大视场 (FOV) 图像。该方法适用于健康受试者和青光眼患者中用偏振敏感 OCT 仪器记录的数据。跟踪和拼接精度被量化，最后，展示了视网膜神经纤维层延迟的大视场图像，其中包含从视神经乳头到中缝的弓状神经纤维束。
