我们提出了一种基于Ascan间散斑去相关的方法，该方法可以定量评估与OCT成像光束方向垂直的血流。为了验证这种方法，我们进行了系统的研究，使用体模和体内动物模型。结果表明，我们的散斑分析方法可以准确地提取横向流速，具有较高的空间和时间分辨率。
We propose an inter-Ascan speckle decorrelation based method that can quantitatively assess blood flow normal to the direction of the OCT imaging beam. To validate this method, we performed a systematic study using both phantom and in vivo animal models. Results show that our speckle analysis method can accurately extract transverse flow speed with high spatial and temporal resolution.
