fNIR Mobile Data System
Part #: fNIR103M, fNIR203M, fNIR303M

High-performance mobile fNIR Imaging Systems are stand-alone functional brain imaging solutions for continuous NIR spectroscopy (NIRS). These top of the line systems provide cognitive function assessment and eliminate a great many of the drawbacks of a functional MRI. Mobile subjects are comfortable and can respond naturally in real-world situations to take a test or perform mobile tasks.

fNIR 2000 Series Advantages

  • Most Flexible–Configurations for various application and the most comprehensive line of sensors in the industry (including new through the hair sensors)
  • Best Value–The lowest price in the industry with cutting-edge engineering, the highest quality material, and robust data collection
  • Shortest Prep Time–easy sensor application, calibration, and baselining shorten preparation time and operator’s learning curve
  • Most Powerful and Friendly Analysis Tools–Implement the most advanced analysis tasks without any programming
  • Least Prone to Systemic and Motion Artifacts–Near Sensors reduce systemic artifacts & software provides tools for post-hoc removal of Systemic Artifact
  • Least Intrusive–18-optode sensor weighs around one once (32 grams)
  • Lower noise almost twice as efficient LEDs
  • Much More Compact
  • Higher Frame Rates up to 10 Hz
  • Two Way Synchronization
  • No Isolation Transformer Required

fNIR is an optical imaging technology that measures neural activity and hemodynamic response in the prefrontal cortex. Subjects wear an fNIR sensor (IR light sources and detectors mounted in a flexible band) on the forehead that detects oxygen levels in the prefrontal cortex and provides real-time values for oxy-hemoglobin and deoxygenated hemoglobin. It provides a continuous and real-time display of the oxygen changes as the subject performs different tasks. The Imager 2000S provides up to 54 channels of information for continuous NIR spectroscopy (NIRS). Systems includes an Imager 2000S control unit, sensors, and software for real-time data viewing and post-acquisition analysis.

fNIR analysis data

The fNIR data combines with other physiological variables such as ECG, respiration, cardiac output, blood pressure, electrodermal activity and stimulus response markers. AcqKnowledge software provides automated analysis tools for event related potentials and ensemble averaging. Combining the fNIR data with the other physiological signals provides researchers with a detailed subject assessment. fNIR is suitable for a wide range of applications, including Human Performance Assessment, Neurorehabilitation, Depth of Anesthesia Monitoring, and Brain Computer Interface. It integrates with stimulus presentation systems and BIOPACs virtual reality products.

fNIRSoft (fS) Pro Edition Software

fS is a stand-alone software package designed to process, analyze and visualize functional near infrared (fNIR) spectroscopy signals through a graphical user interface and/or scripting (for auomation). Use fS viewer tools, data management tools, and a scripting engine to view the data in real time and perform post acquisition analysis. The included fS Pro Edition extends functionality with these additional tools not provided in fS Standard:

  • fS Signal Analysis: Data Processing Tools
  • fS Viewer: Temporal Visualization, Time Series Analysis Tools
  • fS Viewer: Topograph Tools – including brain mapping and visualization over brain surface image

Use fNIR Systems with an MP160 Research System

Synchronize

The Imager 2000M control device has a BNC trigger output that sends TTL pulses at the beginning and end of baseline, and at the beginning and end of a recording session. The trigger can be used to start the MP160 for data collection and to record the start and end of each fNIR segment.

Trigger Acquisition

Connect a BNC to BNC cable between the Imager 2000M control device BNC trigger and the Isolated Digital Interface Module (STP100C), External Trigger port, and set AcqKnowledge to External trigger.

Record Digital Triggers

To record the triggers, connect a Jumper Cable (JUMP100) between the TRIG and one of the Digital I/O lines on the rear of the Universal Interface Module (UIM100C). Turn on the digital I/O line and the system will record and display the triggers on the digital channel.
