Awake chronic mouse model of targeted pial vessel occlusion via photothrombosis [PDF]
, 2020 Animal models of stroke are used extensively to study the mechanisms involved in the acute and chronic phases of recovery following stroke. A translatable animal model that closely mimics the mechanisms of a human stroke is essential in understanding ...

Laser speckle contrast imaging compared with indocyanine green in renal perfusion of a porcine model
Current Urology, 2023 . Background. When viewed under near-infrared light, indocyanine green (ICG) signal for kidney perfusion can be utilized in partial nephrectomy. Laser speckle contrast imaging (LSCI) uses coherent light to detect perfusion during real-time laparoscopic ...

Laser Speckle Modeling and Simulation for Biophysical Dynamics: Influence of Sample Statistics
Journal of Biomedical Photonics & Engineering, 2017 Laser speckle is a statistical phenomenon and should be treated as such when establishing experimental parameters for using laser speckle techniques to infer information about the dynamics of a coherently illuminated medium, such as biological tissue ...

Ultrasound-modulated optical tomography of biological tissue by use of contrast of laser speckles [PDF]
, 2002 Ultrasound-modulated optical tomography based on the measurement of laser-speckle contrast was investigated. An ultrasonic beam was focused into a biological-tissue sample to modulate the laser light passing through the ultrasonic column inside the ...

Imaging depth and multiple scattering in laser speckle contrast imaging [PDF]
Journal of Biomedical Optics, 2014 Laser speckle contrast imaging (LSCI) is a powerful and simple method for full field imaging of blood flow. However, the depth dependence and the degree of multiple scattering have not been thoroughly investigated. We employ three-dimensional Monte Carlo simulations of photon propagation combined with high resolution vascular anatomy to investigate ...

Transmissive multifocal laser speckle contrast imaging through thick tissue
Journal of Innovative Optical Health Sciences, 2023 Laser speckle contrast imaging (LSCI) is a powerful tool for monitoring blood flow changes in tissue or vessels in vivo, but its applications are limited by shallow penetration depth under reflective imaging configuration.
