Hitachi ETG 4100 functional near-infrared spectroscopy (fNIRS)


Philips Neuro (EGI) is pleased to partner with Hitachi to o􀄷er the ETG 4100 Optical Topography system for hemodynamic measurements using near-infrared light. The system transmits near-infrared light through the skull to the cerebral cortex, where the light is absorbed by hemoglobin. These changing concentrations of hemoglobin correspond to regions of activation within the cerebral cortex, providing an effective non-invasive measure of brain activity ideal for use with participants of all ages – neonate through adult.

User-friendly and reliable


The Hitachi system is “plug-and-play” once installed, with a user-friendly software interface and comprehensive user manual. Setting parameters is intuitive, making it straightforward to keep settings consistent across participants for a given study. The software provides useful data visualizations in both real-time and offline. Users can easily move the system between rooms.

Simultaneous multi-channel measurements


Hitachi has developed unique methods for identifying multiple light sources simultaneously, allowing the ETG 4100 to monitor entire brain areas at the same time – regardless of how many light sources and measurement channels are being used. This methodology also eliminates the risk of contamination from ambient light. The ETG 4100 offers many different fiber holders for flexible montages, with a capacity of 24 – 52 channels.

Versatile and high quality


The ETG 4100’s hardware and software make the system well-suited for a wide range of research and clinical applications. Neonate probes and infant fibers are available, allowing for data collection on all ages.

Applications


The ETG 4100 fNIRS system has been engineered for safety and ease-of-use across clinical and research environments. It is actively being used across a range of applications, including: cognitive neuroscience, psychology, psychiatry, neurology, (neuro)rehabilitation, developmental neuroscience, and education.

Support and education

The instrument is not intended for use in diagnosis or treatment of any disease or condition. It is a scientific research instrument designed for performing measurements and acquiring data for neurophysiological research.
