VN415 Vestibular Analysis

vn4151VN415 is a cutting edge product designed for superior computer aided vestibular evaluation. VN415 is Interacoustics’ baseline VNG platform with industry-standard protocols for Spontaneous Nystagmus, Bithermal Caloric, Positional and Dix-Hallpike testing.

VN415 features excellent eye-tracking with high-speed cameras (174 Hz monocular, 105 Hz binocular). The high resolution combined with FireWire® technology gives you real time analysis, very precise measurements and outstanding on-screen video quality.
