We introduce a new type of scanning protocols, called segmented protocols, which enable extracting multi-range flow velocity information from a single Spectral OCT data set. The protocols are evaluated using a well defined flow in a glass capillary. As an example of in vivo studies, we demonstrate two- and three-dimensional imaging of the retinal vascular system in the eyes of healthy volunteers. The flow velocity detection is performed using a method of Joint Spectral and Time domain OCT. Velocity ranging is demonstrated in imaging of retinal vasculature in the macular region and in the optic disk area characterized by different flow velocity values. Additionally, an enhanced visualization of retinal capillary network is presented in the close proximity to macula.
我们引入了一种新型扫描协议，称为分段协议，它能够从单个光谱光学相干断层扫描（Spectral OCT）数据集中提取多范围流速信息。这些协议通过玻璃毛细管中定义明确的流动来进行评估。作为体内研究的一个例子，我们展示了健康志愿者眼睛中视网膜血管系统的二维和三维成像。流速检测使用联合光谱和时域光学相干断层扫描的方法进行。在黄斑区域和具有不同流速值特征的视盘区域的视网膜血管成像中展示了流速范围。此外，在黄斑附近呈现了视网膜毛细血管网络的增强可视化。
