Optical monitoring of cerebral blood flow is a potentially life-saving technology in clinical emergencies, and a number of spectroscopic techniques have been applied to the task. Near-IR spectroscopy ...

Monitoring the flow of blood to the brain can reveal much about how it works. An increase in blood flow usually accompanies neuronal activity, whereas a decrease in the flow can be indicative of ...

Diffuse optical techniques have proven to be valuable methods for non-invasively observing blood flow in living subjects. A number of modalities have been developed, with diffuse correlation ...

Diffuse correlation spectroscopy (DCS) is used for noninvasive detection of blood flow. However, current DCS devices need to be improved to increase the signal-to-noise ratio for more accurate ...

Neurophotonics has published the second part of a comprehensive two-part series that provides an extensive toolkit of optics and photonics technologies for exploring brain health and function. The ...

Cerebral blood flow measurements: Diffuse correlation spectroscopy (DCS) using superconducting nanowire single-photon detectors (SNSPDs) produced 16 times higher signal-to-noise ratio than DCS using ...

“Optical imaging and spectroscopy for the study of the human brain” is the second of two field status reports to be published by Neurophotonics this year BELLINGHAM, Washington, USA — The SPIE journal ...
