functional Near Infrared Spectroscopy
The highest density fNIRS system.
Remarkably ergonomic.
The NIRSIT system is the first fNIRS system that provides millimeter-level spatial resolution while also providing high temporal resolution (125 ms / 8 Hz). The system defied conventional thinking that fNIRS imaging cannot provide comparable spatial resolution to the more expensive and stationary - fMRI and PET systems. NIRSIT is the culmination of three core/ pioneering technologies: 1) dense packing of laser and photo diodes, 2) code-division multiple access (CDMA) and time division multiple access (TDMA) modulation for high temporal resolution, and 3) monolithic IC implementation for high SNR.
The final product is a first of many things:
- First commercial fNIRS system to implement real-time Diffuse Optical Tomography (DOT) resulting in 204 channels that provide 4mm x 4mm spatial resolution
- First truly wireless system (IEEE 802.11 b/g/n), which means users can freely move around while being monitored.
- First truly light, portable, and flexible system, which means you can carry and wear the system easily and anywhere. Adjustable to brain sizes from children to adults.
The NIRSIT System
- Ground breaking joint optimization of system level architecture, circuits and signaling schemes.
- Single IC system for high SNR and size efficiency.
- Light (500 grams), compact, and portable: Just grab and go.
- Easy-to-use: Just follow step-by-step instructions on the tablet app.
- Easy-to-setup: Gain calibration < 1 min.
- Wireless: No wires means that users can freely move around within the range of the network.
- Unmatched Performance: photogrammetry for localization, 6-axis gyroscope and proprietary algorithm for motion artifact removal, save, retrieve and play back data using tablet provided or any computer.
Application Areas
- Neuro-Rehabilitation: Cognitive tasks are typically used in rehabilitation programs to either help in function restoration or learning how to do things differently when function cannot be restored. Monitor progress of rehabilitation strategy by tracking performance gain over time.
- Depression and PTSD: Those affected by Depression and PTSD are commonly assessed for delayed verbal and figural memory, attention and learning. Monitor symptom progression by checking signs of emotional reaction to specific stimulation.
- Concussion: Various tests and tools are employed to assess cognitive and neuropsychological changes post-concussion. In combination with assessment tools, monitor concussion event effects by checking signs of cognitive impairment.
- Education: Monitor progress by checking cognitive performance when performing cognitive and behavioral tasks - for instance by comparing left and right hemisphere brain activation.
NIRSIT by OBELAB is exclusively distributed in the US and Canada by Soterix Medical.
