OxyMon

Our most advanced and versitale fNIRS system

Measure oxy-, deoxy-, and total hemoglobin concentration changes and tissue saturation index in both brain and muscle tissue.


 

fNIRS made easy

 

fNIRS system

The OxyMon is one of the most versatile and fastest NIRS systems on the market. The system monitors a subject’s local tissue oxygenation non-invasively by utilising the technique of near infrared spectroscopy. We offer a wide range of fibers, holders and fit-for-purpose solutions to support you as best as possible and to adept each system to your specific needs. We deliver a set-up enabling you to measure up to 100+ brain channels simultaneously with real time visualization. Our systems have been used for over a decade in hundreds of publications

oxymon Applications

The OxyMon has been used in almost all thinkable fields of research like study the aging brain, the brain at high altitude, functional testing and for brain computer interfacing (BCI). The system can be combined with other techniques such as EEG, TCD or MRI. We even offer fully integrated NIRS/EEG packages

 

The near infrared spectroscopy technique

 

Oxymon highlights

  • Stable, versatile and highly sensitive 
  • Possible to measure on both brain and muscle tissue 
  • Numerous configurations, from 1 to 100+ channels 
  • Fast data collection at 50 Hz as standard - up to 250 Hz possible, for any amount of channels 
  • No need to screen against ambient light 
  • Unlimited data storage 
  • The light detector cannot be damaged by ambient light 
  • Raw data (optical densities) easily accessible 
  • Up to 4 wavelengths per channel

how it works

Near infrared spectroscopy, (NIRS), the technique on which the OxyMon is based, relies mainly on two characteristics of human tissue. Firstly, the relative transparency of tissue for light in the NIR range, and secondly on the oxygenation dependent light absorbance of hemoglobin.

Real-time processing of fNIRS data in 3D

 

Up to a 112 channel fNIRS setup

We offer OxyMon systems from 1 channel up to 112 channels. The 112 channel setup includes a custom build cart and enables you to measure on four subjects simultaneously.  Our system is built up from cabinets. With one cabinet, you can make a maximum of 8 channels. By combining multiple cabinets, more channels can be made. The cabinets can be stacked and used as one big system, but every cabinet also works as an independent smaller system.

Software

All of our devices are bundled with Oxysoft. Oxysoft is our dedicated software application used to collect, store, view, and analyse all necessary data from the OxyMon. This user-friendly software is developed by Artinis and highly customisable to individual requirements. Oxysoft provides in real-time the calculation of oxy-, deoxy-, total hemoglobine and TSI. 


OxyMon fibers

Optical fibers

The customization of the OxyMon does not stop at the number of channels or optode template. For creating your ideal OxyMon system we have a selection of fibers to choose from. Besides, we have redesigned our fibertips to make them lighter, sturdier, and more comfortable for the subject. This makes the OxyMon ideal for the measurement on infants, children and vulnerable subjects. The tip is made out of plastic, this makes all our new fibers compatible with electromagnetic fields. We will always advice you which type of fibers to use depending on your application. We offer the following optical fibers:

  • Receivers/transmitters
  • 1- or 2-end fibers.
  • Straight- or 90°-end fibers
  • 3- or 10-meter fibers.
  • Metal or plastic fiber ends.
  • MRI compatible fibers
  • Extra small rodent fibers
  • Metal shield fibers
  • 8-channel reference fibers
  • Standard or customized fibers.
 

fNIRS headcap

 

Oxymon headcap

At Artinis we designed and developed our own headcap. This headcap shows major improvements over the other commonly used NIRS headcaps, such as EEG caps. In comparison to the standard caps it covers the entire scalp and prefrontal cortex, provides equally divided pressure, freedom of head movement for the subject and absorbs external light due to it's fabric.

All headcaps show printed optode marks and 10/20 system indications.
You are able to create your own custom optode template with the delivered tool. 

Sizes available: XXS, XS, S, M, L, XL.
Besides headcaps we also offer holders for muscle measurements.
