Diffuse optical imaging of the whole head.
Maria Angela Franceschini,Danny K. Joseph,Theodore J. Huppert,Solomon G. Diamond,David A. Boas +4 more
TL;DR: Whole-head optical measurements, in addition to providing maps of multiple brain regions' responses to brain activation, will enable better understandings of the physiological signals, ultimately leading to better signal processing algorithms to distinguish physiological signal clutter from brain activation signals.
Diffuse optical tomography of pain and tactile stimulation: activation in cortical sensory and emotional systems.
TL;DR: The results suggest that based on the temporal and spatial characteristics of the response in the sensory cortex, it is possible to discern painful from mechanical stimulation using DOT and might have potential applications in a clinical setting in which pain needs to be assessed objectively.

Design and Validation of a Diffuse Optical Tomography System with Improved Spatial Resolution for Functional Brain Imaging
TL;DR: In this article, a diffuse optical tomography system that combines frequency encoding with time-division multiplexing to enable overlapping measurements of brain activation is described, which is confirmed by functional magnetic resonance imaging.

Time Domain Optical Imager for Depth-Resolved 1.8 Hz Functional Imaging of the Adult Head
TL;DR: In this paper, a 32 source, 18 detector time-gated system using a pulsed laser and an ICCD camera was developed for functional imaging of both hemispheres with depth discrimination.
Time-gated optical system for depth-resolved functional brain imaging.
TL;DR: A time-domain optical system based on a Ti:Sapphire pulsed laser and an intensified CCD camera enabling parallel detection of multiple fibers for functional brain imaging shows discrimination between superficial and cortical responses to the stimulus on both hemispheres.
