提出了一种结合线光束扫描照明的横向激光散斑衬度分析方法，以提高血流成像的采样深度。体模和动物实验结果均表明，与传统的全场照明激光散斑衬度分析方法相比，局部照明和侧向散斑衬度分析可以显著增强深部血流信号，提高激光散斑衬度成像的采样深度。
We present a lateral laser speckle contrast analysis method combined with line beam scanning illumination to improve the sampling depth of blood flow imaging. Both the phantom and animal experimental results suggest that localized illumination and lateral speckle contrast analysis can significantly enhance the deep blood flow signal to improve the sampling depth of laser speckle contrast imaging compared with the traditional full-field illumination laser speckle contrast analysis method.
