VHIT Ulmer (system)

The VHIT enables to test all 6 semi-circular canals at high frequency as well as the saccades strategies (overt and covert)

- Fast test : 5 minutes to test the 6 canals and detect saccades (overt and covert) and to obtain a complete and relevant analysis
- Non invasive test : no mask or device on patient’s head thanks to remote camera
- Independant analysis of the 6 semi-circular canals through fast head movements
- Simultaneous observation of eye and head movements thanks to remote camera
- Maneuvers simple to carry out : automatic detection of the tested canal and visual information given by software in real time + maneuver guide
- 2 scalable software versions : from VHIT SCREENING (lateral canals only) to VHIT EVOLUTION (6 canals)
- No disposable (because of remote camera)

DESCRIPTION

Combined to the VNG Ulmer that tests the lateral canals at low and medium frequencies, the VHIT enables to obtain a complete analysis.
