NIRScout High Density, Scalable Neuroimaging Platform

The NIRScout is a user-friendly, modular, and robust functional near-infrared spectroscopy (fNIRS) platform which measures hemodynamic neuroactivation via oxy-, deoxy-, and total hemoglobin changes in the cerebral cortex. The NIRScout platform includes a host of ready-to-implement upgrades and modules to meet the needs of a broad range of cognitive neuroscience applications.


Freely-configurable probe arrays easily integrate with EEG and tDCS within a single NIRx NIRScap. Concurrent fNIRS + fMRI and fNIRS + TMS may be done with the NIRScout’s low-profile fiber-optic probes.

NIRscout comes in two models: Standard and Extended. Either model may be upgraded by 8-source and 4-detector increments. Systems range from 8-source 4-detector (32 data channels), to 128-source 64-detector tandem configurations (4096 data channels).

NIRScout can measure both topographics and tomographic NIRS data from the entire cortex, yeilding 3D depth discrimination neurosctivation. Optical sources are available in in standard LED (2 wavelengths) configuration or Laser (4 wavelengths) with the NIRScout hybrid LED/Laser source module.

Key Advantages

  • Ultra-high-density lab-based fNIRS systems available
  • Can be upgraded in 8-source and 4-detector increments up to 64 sources and 32 detectors
  • Measures ultra high-resolution NIRS functional images e.g. 5mm spatial resolution with 7.5mm probe spacing
  • Ideal for use with lightweight flat probes – does not require optical coupler for detectors
  • Can be upgraded to use fiber optic 8-wavelength laser sources for more thoroughly analyzing the hemoglobin signal: allows enzyme and connectivity-related studies
  • Ideal system for use with TMS and fMRI
  • Capable of short-distance (close to 0mm, co-located) multi-distance (tomography, 3D depth) measurements
  • Illumination pattern (source firing sequence) fully-customizable, which increases sampling rate
  • Can measure up to 8 subjects from a single system
  • Up to 255 triggers input, and up to 255 triggers output (NIRSport has 15 trigger-input only)
