fNIR Systems

NITRS optical brain imaging

Complete fNIR Functional Near Infrared Optical Imaging Systems

BIOPAC provides a range of fNIR systems, from basic to complete. Select a wireless or wired fNIR imager and sensor to use with your computer, or add one or two computers and accessories to suit your protocol. Each fNIR system provides real-time monitoring of tissue oxygenation in the brain as subjects take tests, perform tasks, or receive stimulation, allowing  researchers to quantitatively assess brain functions—such as attention, memory, planning, and problem solving—while individuals perform cognitive tasks. fNIR devices provide relative change in hemoglobin levels, calculated using a modified Beer-Lambert law. Powerful spectroscopy imaging tools measure NIR light absorbance in blood of hemoglobin with and without oxygen and provide information about ongoing brain activity, similar to functional MRI studies. 

fNIR provides a safe, affordable, noninvasive solution for cognitive function assessment and eliminates many of the drawbacks of MRI.
