Circulatory shock is a leading global cause of death and disability in children. Shock is defined as a life-threatening condition where cardiovascular system failure causes inadequate delivery of ...
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 ...
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 ...
“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 ...
Cerebral blood flow is essential for normal brain function and often perturbed in neurological disease. If one shines a source of coherent light on perfused tissue, the detected speckles, or “grains” ...
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 ...
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 ...
