NIRX is a world-leader in providing integrated solutions for fNIRS neuro-imaging.  In 1988 we introduced the concept of tomographic imaging (i.e., multi-distance measurements) in dense scatted media base on diffusely scattered light. This approach has since been widely adapted and has served to launch the modern day field of fNIRS tomography.

Through our offices in Berlin, Los Angeles, New York and São Paolo, our engineers and grant-funded investigators are providing a growing number of research teams world-wide with comprehensive technology solutions for the most demanding investigative applications.


Exploring Optical Neuroimaging

NIRx was founded by functional near-infrared spectroscopy (fNIRS) researchers.  We continue to focus 100% of our efforts to advancing and promoting this innovative and promising research tool.

NIRx believe in the importance of constantly contributing new information to the fNIRS community.  We are always adding to our downloadable material and hope you will learn something!
