A survey of optical imaging and spectroscopy for the study of the human brain has reported that the field is currently "only at the beginning of this optical revolution." Published in SPIE ...

Diffuse correlation spectroscopy (DCS) can assess blood flow non-invasively, by analyzing diffused light returning from illuminated areas of tissue and detecting the speckled spectral signals of blood ...

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 ...

An increase in intracranial pressure (ICP) is a dangerous condition that can be caused by brain bleeds, a brain tumor, cerebral edema, traumatic brain injury, and hydrocephalus. ICP monitoring is thus ...

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 ...

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 ...
