Laser speckle contrast imaging in biomedical optics [PDF]

Journal of Biomedical Optics, 2010
First introduced in the 1980s, laser speckle contrast imaging is a powerful tool for full-field imaging of blood flow. Recently laser speckle contrast imaging has gained increased attention, in part due to its rapid adoption for blood flow studies in the brain. We review the underlying physics of speckle contrast imaging and discuss recent developments

Spatiotemporal laser speckle contrast analysis for blood flow imaging with maximized speckle contrast

Journal of Biomedical Optics, 2010
Laser speckle contrast imaging is a technique used for imaging blood flow without scanning. Though several studies have attempted to combine spatial and temporal statistics of laser speckle images for reducing image noise as well as preserving acceptable spatiotemporal resolution, the statistical accuracy of these spatiotemporal methods has not been ...

Clinical applications of laser speckle contrast imaging: a review [PDF]

Journal of Biomedical Optics, 2019
When a biological tissue is illuminated with coherent light, an interference pattern will be formed at the detector, the so-called speckle pattern. Laser speckle contrast imaging (LSCI) is a technique based on the dynamic change in this backscattered light as a result of interaction with red blood cells. It can be used to visualize perfusion in various

Application of laser speckle contrast imaging in laparoscopic surgery

Biomedical Optics Express, 2019
Anastomotic leakage is a worldwide problem in gastrointestinal surgery which seems to be related to the state of microcirculation. Laser speckle contrast imaging (LSCI) could give surgeons insight in the state of microcirculation to attune the site of anastomosis. This work studies the feasibility of LSCI as a tool for this purpose.

Laser Speckle Contrast Imaging in Neurosurgery: A Systematic Review

World Neurosurgery, 2023
Intraoperative study of blood flow in the brain vessels is among the most critical topics of modern neurosurgery. One of the promising methods for intraoperative monitoring of blood flow is laser speckle contrast imaging (LSCI). This systematic review aims to analyze the experience of using intraoperative LSCI in neurosurgical interventions.The ...

Laser speckle contrast imaging: theoretical and practical limitations [PDF]

Journal of Biomedical Optics, 2013
When laser light illuminates a diffuse object, it produces a random interference effect known as a speckle pattern. If there is movement in the object, the speckles fluctuate in intensity. These fluctuations can provide information about the movement.
