Laparoscopic Laser Speckle Blood Flow Imaging Technology
Laser speckle contrast imaging (LSCI) technology is widely used in tissue surface blood flow imaging with large field of view. When real-time in vivo monitoring of blood flow distribution and changes in deep tissue or lumen tissue is needed, the combination of LSCI and endoscopic imaging is an effective way to solve the problem of LSCI imaging depth. For this reason, a commercial laparoscopic LSCI imaging system is built to image microfluidic replicas and rabbit large intestine. The experimental results show that the system can correct the static scattering and eliminate the influence of system noise on speckle contrast, and the quantitative monitoring of blood flow can be realized by using the speckle contrast measurement under single exposure. The commercial laparoscopic LSCI imaging system will have important clinical application potential.
