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 ...

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 ...

Diffuse optical measurement techniques employ near-infrared light to non-invasively probe cerebral haemodynamics by assessing both absorption and scattering properties of brain tissue. Methods such as ...

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 ...

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 ...

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 ...

A project at Spain's ICFO research center has employed diffuse optics in a platform designed to monitor thyroid health, to assist disease diagnosis and therapy. Thyroid diseases affect 200 million ...
