Journal ArticleDOI
Robust flow measurement with multi-exposure speckle imaging.
TL;DR: A new Multi-Exposure Speckle Imaging (MESI) instrument that has potential to obtain quantitative baseline flow measures and a new speckle model which can discriminate flows in the presence of static scatters is presented.
Journal ArticleDOI
Diffuse correlation spectroscopy for measurement of cerebral blood flow: future prospects.
Erin M. Buckley,Ashwin B. Parthasarathy,P. Ellen Grant,Arjun G. Yodh,Maria Angela Franceschini +4 more
TL;DR: Future applications where DCS may play a pivotal role individualizing patient management and enhancing the understanding of neurovascular coupling, activation, and brain development are highlighted.
Journal ArticleDOI
Modified Beer-Lambert law for blood flow
Wesley B. Baker,Ashwin B. Parthasarathy,David R. Busch,Rickson C. Mesquita,Joel H. Greenberg,Arjun G. Yodh +5 more
TL;DR: A Modified Beer-Lambert law for blood flow based on diffuse correlation spectroscopy (DCS) measurements is developed and validated and is particularly well-suited for utilization with pressure measurement paradigms that employ differential flow signals to reduce contributions of superficial tissues.
Journal ArticleDOI
Laser speckle contrast imaging of cerebral blood flow in humans during neurosurgery: a pilot clinical study
TL;DR: Results from this study demonstrate the feasibility of using LSCI to obtain blood flow images during neurosurgeries and its capability to produce full field CBF image maps with excellent spatial resolution in real-time with minimal disruption to the surgical procedure.
Journal ArticleDOI
Quantitative imaging of ischemic stroke through thinned skull in mice with Multi Exposure Speckle Imaging
TL;DR: The MESI technique was used to image the blood flow changes in a mouse cortex following photothrombotic occlusion of the middle cerebral artery and estimates of these flow changes were found to be unaffected by scattering from thinned skull.
