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 ...

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 ...

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 ...

Why is Diffuse Reflectance Spectroscopy Used? One of the main techniques for evaluating the optical properties of materials is optical absorption spectroscopy, or UV-vis spectroscopy. Most absorption ...

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 ...

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 ...

The Drexel Ultrasound and Optics Wound Healing Team was formed as a collaboration between the ultrasound work of Dr. Peter A. Lewin and the optics team of Drs. Michael S. Weingarten and Leonid Zubkov ...
