Induction and imaging of photothrombotic stroke in conscious and freely moving rats.
TL;DR: A rodent model of focal cerebral ischemia and real-time blood flow imaging opens the possibility of performing various fundamental and translational studies on stroke without the influence of anesthetics.

Predicting the ischemic infarct volume at the first minute after occlusion in rodent stroke model by laser speckle imaging of cerebral blood flow
TL;DR: An on-line laser speckle imaging (LSI) system is implemented, which could provide real time high spatio-temporal resolution CBF information before, during, and immediately after the rat MCAO surgery, and finds a significant correlation between the affected area with 50% CBF reduction at the first minute after occlusion with the infarct volume.

Directly measuring absolute flow speed by frequency-domain laser speckle imaging.
TL;DR: A frequency-domain laser speckle imaging (FDLSI) method that can directly measure absolute flow speed is presented and in vivo experiments demonstrated that FDLSI was minimally affected by illumination condition changes.

TL;DR: This study shows real-time CBF changes during and immediately after asphyxial-CA, with high spatial and temporal resolution images and finds that the velocity of venule blood flow increased more than that of the arteriole blood flow during the hyperemia.
Real-time high resolution laser speckle imaging of cerebral vascular changes in a rodent photothrombosis model
TL;DR: Real time CBF and BVP monitoring has been shown to reveal details of vascular disturbances and the stages of blood coagulation in photothrombotic stroke and LSI provides information on additional parameters including vessel morphologic size, blood flow centerline velocity and CBF spatiotemporal fluctuations, which are very important for understanding the physiology and neurovascular pathology in the photothROMbosis model.
