VisualSystem HD

High-end visual stimulation for fMRI


NordicNeuroLab VisualSystem HD is a sophisticated and flexible solution for presenting visual stimuli inside the MR scanner. By rendering sharp images and brilliant colors, high quality graphics or text is presented to the patient.

The VisualSystem HD has a design which fits most head coils, and it is easy to mount with coil specific adapters. The adjustable arm allows fast and precise positioning at the preferred angle of view. The built-in diopter correction and fine-tuning of pupil distance are easy to regulate and customize to each patient, both adult and children.

Scientific studies indicate that the presentation of visual stimuli in fMRI experiments is more reliable with direct input through video goggles than with the use of conventional projection systems. Because the VisualSystem HD is placed close to the eyes, there are no external distractions during stimulus presentation, and individuals are also less likely to experience discomfort related to the confined space of the MR scanner.

The VisualSystem interfaces seamlessly with our nordicAktiva stimulus presentation software and our new nordicComfortPlayer for the most streamlined workflow available.

Advanced users can also benefit from the integrated binocular eye-tracking.


Our new VisualSystem HD offers some of the most advanced features available today:

  • Full HD resolution displays (1920 x 1200)
  • Integrated binocular eye-tracking
  • Support for 3D / Stereoscopic
  • Built-in diopter- and pupil-distance adjustment
