Our Technology

Neurolign Dx Platform

The Neurolign Dx Platform is a single connected system offering seamless integration, whether you operate one or all of our products. From the Neurolign Dx 100™ to the Neurolign Dx NOTC – you can do it all, with a single software platform.

Comprised of two systems that work in tandem:

1) I-Portal® collects all eye-tracking data which is transferred into VEST for storing, viewing and analysis, and;

2) VEST™ operates testing, analysis and reporting of results

VEST™ Software

  • FDA cleared normative data for reference range comparisons
  • Ability to compare individual performance over time with repeat assessments
  • Baseline Health Assessment, including full battery of oculomotor, vestibular, reaction time and cognitive tests
  • Clinical expert and research access to create custom assessments (Custom Assessment)
  • Real time binocular eye-tracking data and immediate analysis for efficient data assessment and interpretation
  • Updated Brain Health Assessment report to support ease of use and interpretation
  • Ability to print out detailed data within analysis mode

I-Portal® Software

I-Portal® software captures processes and analyzes high speed digital images of the eye, calculating horizontal, vertical, torsional, and pupil data. I-Portal works with binocular goggles to track each eye separately. This allows for conjugacy measurements and identifies any differences in the performance of each eye.

  • Eye-tracking and stimulus are synchronized in real time
  • Neurolign’s proprietary geometric algorithms reliably track the pupil with an unmatched 0.1 to 0.02 degree of accuracy
  • Only Neurolign captures images at 99.996 Hz (Variability at only 0.24%)
  • Our patented technology focuses precisely on the specific eye region of interest, providing data on areas often unidentified

Diagnostic Devices

Neurolign offers a portfolio of devices for clinical medical professionals responsible for diagnosing and treating vestibular and neurotologic patients.

Neurolign Dx devices are engineered to measure neural functions and symptoms associated with an extensive array of diseases and conditions using a battery of OVRT (oculomotor, vestibular and reaction time) tests.

Neurolign Dx 100™

The Neurolign Dx 100™ is a head mounted non-invasive goggle with integrated clinical eye tracking and digital display. FDA cleared (K171884) features include:

  • Our baseline Health Assessment containing a full battery of oculomotor, vestibular, reaction time and cognitive tests. Our tests and output variables are the most comprehensive and precise on the market today. We also offer unique tests including vergence, optokinetic and reaction time tests making us the most comprehensive neurological health assessment on the market
  • Grounded in clinical science and research, we are continuing to create new tests to launch to the broader market including light reflex
  • FDA approved reference range data for normative comparisons
  • Ability to compare individual results over repeat assessments
  • Full field 2-D and 3-D visual stimulus for patients to track
  • 4D eye tracking: torsional, horizontal, vertical and patented pupillometry measurements
  • On-board 3 degree of freedom motion sensor
  • Separate, synchronized left and right eye stimulus and measurements
  • Neurolign Dx 100™ is effective for baseline testing, creating precise and effective treatment protocols and monitoring overall. Patients enjoy seeing their results over time for both their individual performance and compared to FDA approved reference range data

Neurolign Dx SVNG-2

The Neurolign Dx SVNG-2 provides a quick and efficient way to add real world vestibular testing without the space required for the larger rotary chair systems while still adding OVRT diagnostic capability to your clinic. The SVNG-2 uses the same full field OKN and Pursuit Tracker® laser diode technology as the Neurolign Dx NOTC. These, and other components, are mounted on a medical grade cart for greater mobility when needed, such as when transitioning between suites to conduct caloric, positional and positioning tests. The Dx SVNG-2 includes:
