我们应用可见光光谱光学相干断层扫描(vis-OCT)在体内视网膜血氧饱和度。为了提取单个视网膜血管中的血红蛋白氧饱和度(sO2),我们建立了一个全面的分析模型来描述全血中的光吸收、光散射和血细胞填充因子,并拟合从每个成像血管底部采集的vis-OCT信号。我们发现,动脉和静脉血中的平均sO2值分别为95%和72%。
We applied a visible-light spectroscopic optical coherence tomography (vis-OCT) for in vivo retinal oximetry. To extract hemoglobin oxygen saturation (sO2) in individual retinal vessels, we established a comprehensive analytical model to describe optical absorption, optical scattering, and blood cell packing factor in the whole blood and fit the acquired vis-OCT signals from the bottom of each imaged vessel. We found that averaged sO2 values in arterial and venous bloods were 95% and 72%, respectively.
