From pure research to clinical applications

ETG-4100 uses near-infrared light of distinct wavelengths to measure changing concentrations of oxygenated and deoxygenated hemoglobin levels in the brain.
The system can simultaneously measure the entire measuring area and can be used under daytime / artificial conditions.

The system software is the "all-in-one" solution.
From experimental design to measurement, from raw data to analysis, the ETG-4100 combines all tools in a single suit.
