Several clinical conditions leading to traumatic brain injury can cause hematomas or
edemas inside the cerebral tissue. If these are not properly treated in time, they are prone to …

Previous methods for analyzing optical imaging data have relied heavily on temporal
averaging. However, response dynamics are rich sources of information. Here, we develop …

Functional near-infrared spectroscopy (fNIRS) is an optical method for noninvasively
determining brain activation by estimating changes in the absorption of near-infrared light …

The in-vivo optical properties of the human head are investigated in the 600–1100 nm range
on different subjects using continuous wave and time domain diffuse optical spectroscopy …

The optical properties of neural tissues play critical roles in all types of optical imaging
methods. The wavelength-dependent absorption and scattering properties of tissue …

Diffuse optical imaging can measure brain activity noninvasively in humans through the
scalp and skull by measuring the light intensity modulation arising from localized-activity …

A spectroscopic imaging device to study brain activation, without any scan nor contact, is
under construction. The entire instrument will be assembled in a unique setup and will use …

This review describes the unique opportunities and challenges for noninvasive optical
mapping of human brain function. Diffuse optical methods offer safe, portable, and radiation …

An optical tomographic imaging system that is composed of 32 near infrared time-resolved
spectroscopic channels has been newly implemented for the experimental evaluation of …

Diffuse optical imaging is a non-invasive technique for measuring changes in blood
oxygenation in the brain. This technique is based on the temporally and spatially resolved …
