| Zusammenfassung | We report on the design and first in vivo tests of a novel noncontact scanning imaging system for time-domain near-infrared spectroscopy. Our system is based on a null source-detector Separation approach and utilizes polarization-selective detection and a fast-gated single-photon avalanche diode to record late photons only. The in-vivo tests included the recording of hemodynamics during arm occlusion and two brain activation tasks. Localized and non-localized changes in oxy- and deoxyhemoglobin concentration were detected for motor and cognitive tasks, respectively. The tests demonstrate the feasibility of non-contact imaging of absorption changes in deeper tissues. |
