Abstract

We present a lightweight TD-NIRS system, two-wavelength, one detection channel that can be battery operated and worn as a backpack for freely-moving cerebral and muscle hemodynamic monitoring. Oxy- and deoxy-genated hemoglobin absolute concentration can be retrieved in real time even in outdoor measurements thanks to the rugged feature of the device.
