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

RXFNIR-PED Pediatric | 2 | 2 | 1 |20 mm |all Imagers

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

Note: RXFNIRA was discontinued October 2017; sensor was Adult | 16 |10 | 4 | 25 mm | tethered Imager 1200 and required RXFNIR-SEN-CBL.

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.

  • The phantom is included with the fNIR400 System and can be added to fNIR100A, fNIR200A, or fNIR300A Systems.

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.

fNIR Phantom self-test

Cleaning fNIR Imagers and Sensors

All generations and models: Use an alcohol swab to gently wipe the surface of the fNIR Imager unit or sensor.

New Citations | Breath of Life

With new developments happening daily, it’s easy to forget to slow down and take a breath. Breathing can be as forgettable as it is crucial; the often forgettable automatic function inspires rituals in religions around the world. Studies have shown the importance of breathing not just in a spiritual sense but also in physiological health benefits. Lung functionality […]
