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 ...

In the field of clinical instrumentation and life science research, sensing and optical spectroscopy perform vital roles in a range of applications. Optical spectroscopy offers an optimal method for ...

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 ...
