Interacoustics
Interacoustics - VNG
Complete solutions for balance testing. Video Nystagmography provides ideal conditions for the observation, measurement and analysis of eye movements. It saves time, reduces costs and avoids the problems of myogenic and electrical noise.
VN415 Vestibular analysis
The VN415 is designed for convenient computer aided analysis of positional and caloric tests. Rapid data transfer technology enables very high quality video and precise measurements with all results stored in the OtoAccess™ database. The system also includes functions for printing reports and sharing data.
Connect and go
VN415 is a completely portable VNG system. There is no bulky equipment to get in the way. Start the software, place the goggles on the patient and you are ready to test.
High quality video and analysis
The VN415 performs real time analysis. Rapid data transfer (105 Hz binocular, 174 Hz monocular) allows much more data to be analysed, giving very precise measurements and outstanding video quality.
Vestibular test battery
The VN415 test battery includes Spontaneous Nystagmus, Dix-Hallpike, Positional and Bithermal Caloric tests. You can design your own test protocols and load these with a single mouse click.
Remote controlled testings
It is possible to step through the tests using the USB connected footswitch.
Video recording
The video from each test can be recorded and stored in full on the associated storage device (typically a hard drive) where it is linked to the results in the database record. The only limit to the size of the recording is the capacity of the recording device. When the session is reviewed, the recording will be available for replay in normal, fast or slow mode. There is also the option to review the recording one beat at a time. The recording can be exported in AVI format for consultation or teaching purposes. Various sound file formats are available to include sound recording together with the video.

VO425 Vestibular & Oculomotor analysis
The VO425 is designed for clinics that carry out detailed balance evaluations. It contains all the features of the VN415 plus computer aided analysis of oculomotor tests. Rapid data transfer technology enables high quality video and precise measurements, with all results stored in the OtoAccess™ database. The system also includes functions for printing reports and sharing data.
Software generated ocular stimuli
Full field of view visual stimuli are software generated from your laptop or PC connected to a video projector or an LCD screen. The digital stimuli are ideal for both pediatric and adult populations and include several default patterns, e.g. stripes, chessboards and cartoons for the children. In addition you can import your own stimuli patterns.
Complete balance testing
Tests include automated calibration, Spontaneous Nystagmus, Gaze, Tracking, Saccade, Optokinetics, Positional, Hallpike and Bithermal/Monothermal Caloric. Easily design your own test protocols, which can be loaded with a single mouse click.
Automatic or manual analysis
The system produces highly accurate test results, but you can switch to manual edit mode in all tests to overrule the automatic analysis. In manual edit mode you can add or delete nystagmus marks, change slopes and define alternative areas of analysis.
Sharing results
The VO425 is designed to facilitate collaboration. All results are stored in the OtoAccess™ database with abilities for printing detailed colour reports. Results and recordings can also be exported for electronic charting purposes.
