Journal ArticleDOI
Time-resolved multidistance near-infrared spectroscopy of the adult head: intracerebral and extracerebral absorption changes from moments of distribution of times of flight of photons
Adam Liebert,Heidrun Wabnitz,J. Steinbrink,Hellmuth Obrig,M. Möller,Rainer Macdonald,Arno Villringer,Herbert Rinneberg +7 more
TL;DR: Multidistance time-resolved diffuse reflectance spectroscopy of the head of a healthy adult after intravenous administration of a bolus of indocyanine green is reported on.
Journal ArticleDOI
Bed-side assessment of cerebral perfusion in stroke patients based on optical monitoring of a dye bolus by time-resolved diffuse reflectance.
Adam Liebert,Heidrun Wabnitz,Jens Steinbrink,M. Möller,Rainer Macdonald,Herbert Rinneberg,Arno Villringer,Hellmuth Obrig +7 more
TL;DR: The study demonstrates the necessity of a technique with sub-nanosecond time resolution to allow for depth discrimination if clinical perfusion monitoring of cerebrovascular diseases is addressed by optical methods.
Journal ArticleDOI
Evaluation of optical properties of highly scattering media by moments of distributions of times of flight of photons
TL;DR: The moment analysis may serve as a comparatively fast method for evaluating optical properties with sufficient accuracy and can be used, e.g., for on-line monitoring of optical properties of biological tissue.
Journal ArticleDOI

TL;DR: In this paper, a multi-center study has been set up to accurately characterize the optical properties of diffusive liquid phantoms based on Intralipid and India ink at near-infrared wavelengths.
Journal ArticleDOI

TL;DR: The "Basic Instrumental Performance" protocol for direct measurement of relevant characteristics is presented and the relevance of the responsivity measure is demonstrated by simulations of diffuse reflectance as a function of source-detector separation and optical properties.
