As a pioneer and leading manufacturer of fNIRS technology, Hitachi developed ETG-4100 – the next generation optical topography system.

This model has advanced features and innovative applications that can deliver high quality data of changing haemoglobin concentrations in the cerebral cortex.

The New Generation of functional Near-Infrared Spectroscopy (fNIRS)

The development of Optical Topography, a non-invasive imaging method to study cerebral hemodynamics has paved the way for new functional brain imaging. Over the past few decades, several studies have been conducted and validated the suitability of this technology for a wide variety of populations and applications to investigate the working brain. Its capability to allow measurements in everyday-life scenarios without practical limitation like with fMRI has led to advancements in the study of neurocognitive processes in unconstrained environment.

The state-of-the-art ETG-4100 uses the fNIRS to study cerebral blood flow and is available in different measurement channels configurations for a wide variety of research and clinical applications.
