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
Time-domain optical mammography: initial clinical results on detection and characterization of breast tumors
Dirk Grosenick,K. Thomas Moesta,Heidrun Wabnitz,Jörg Mucke,Christian Stroszczynski,Rainer Macdonald,Peter M. Schlag,Herbert Rinneberg +7 more
TL;DR: Effective tumor optical properties derived from a homogeneous model were used to deduce physiological information and all tumors exhibited increased total hemoglobin concentration and decreased or unchanged blood oxygen saturation compared with surrounding healthy tissue.
Journal ArticleDOI
Performance assessment of photon migration instruments: the MEDPHOT protocol
Antonio Pifferi,Alessandro Torricelli,Andrea Bassi,Paola Taroni,Rinaldo Cubeddu,Heidrun Wabnitz,Dirk Grosenick,M. Möller,Rainer Macdonald,Johannes Swartling,Tomas Svensson,Stefan Andersson-Engels,Robert L. P. van Veen,Henricus J. C. M. Sterenborg,Jean-Michel Tualle,Ha Lien Nghiem,Sigrid Avrillier,Maurice Whelan,H Stamm +18 more
TL;DR: A comprehensive protocol for the performance assessment of photon migration instruments based on five criteria: accuracy, linearity, noise, stability, and reproducibility is proposed.
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.
