fNIR Sensor Replacement for Optical Brain Imaging
Part #: RXFNIR-4, fNIR-Phantom

Functional near infrared optical brain imaging forehead (prefrontal cortex) sensor pads connect to fNIR System Imager unit to provide real-time oxy-Hb, deoxy-Hb, and raw data values for each channel measurement area.

PART # | Channels | Detectors | Emitters | Inter-optode Distance | Interface

RXFNIR-4 Split | 4 | 4 | 2 |25 mm | all Imagers

FNIR-PHANTOM | mimics optical properties of brain tissue to test sensor performance |≥ Imager 1100

Note: RXFNIRA Adult | 16 |10 | 4 | 25 mm | was discontinued October 2017; sensor interfaced tethered Imager 1200 and required RXFNIR-SEN-CBL. RXFNIR-PED Pediatric | 2 | 2 | 1 |20 mm was discontinued September 2020; contact BIOPAC to discuss sensor options for children 2 yrs and up.

Details

Compatibility


Photo-detectors: Silicon photodiode with integrated trans-impedance preamp

Photo-emitters: 730 nm/850 nm dual wave-length LED

Material: silicone rubber over-molded

Phantom Sensor

The phantom sensor material mimics optical properties of brain tissue, and it is used to test the system to make sure that the fNIR sensor is detecting correctly.

See the fNIR COBI Manual for details on how to run a Self-Check to test signal levels at each channel and generate a report that indicates performance on each channel.

Cleaning fNIR Imagers and Sensor

All generations and models: Use an alcohol-based antiseptic to gently wipe the surface of the fNIR Imager unit or sensor; never use peroxide-based antiseptics.
