Quantitative blood flow velocity imaging using laser speckle flowmetry.
Laser speckle flowmetry suffers from a debated quantification of the inverse relation between decorrelation time (τc) and blood flow velocity (V), i.e. 1/τc = αV. Using a modified microcirculation imager (integrated sidestream dark field - laser speckle contrast imaging [SDF-LSCI]), we experimentally investigate on the influence of the optical properties of scatterers on α in vitro and in vivo....
متن کاملImaging Retinal Blood Flow with Laser Speckle Flowmetry
Laser speckle flowmetry (LSF) was initially developed to measure blood flow in the retina. More recently, its primary application has been to image baseline blood flow and activity-dependent changes in blood flow in the brain. We now describe experiments in the rat retina in which LSF was used in conjunction with confocal microscopy to monitor light-evoked changes in blood flow in retinal vesse...

Laser speckle flowmetry suffers from a debated quantitative relationship with blood flow, velocity or tissue perfusion and a lack of calibration of the inverse relationship 1/τc = αV between decorrelation time (τc) and flow velocity (V). Using a modified microcirculation imager, we experimentally investigate on the influence of the optical properties of scatterers on α in vitro and in vivo. We ...
