True HSV Imaging supercedes Videostroboscopy.
High-speed videoendoscopy (HSV) captures the true intra-cycle vibratory behavior of the vocal folds, overcoming the limitations of videostroboscopy for more accurate objective quantification methods.The intracycle vibration seen when viewing videostroboscopy displays an illusory “slow motion”, produced by sequencing different phases of the glottal cycle, it’s not real and will completely fail for voices with middle and high degree of dysphonia because of the dependency on a “good” pitch tracking through microphone.
High speed videoendoscopy overcomes the limitations of stroboscopy and offers a true and real view at the vocal folds.
lingWAVES 4 HSV, a commercially available and tested system for high speed videoendoscopy, offers a wide range of valid, practical and clinical relevant information for laryngeal assessment based on modern streaming high speed capture technology.
Smart Hardware with Streaming Technology
They huge and heavy in the past – high speed cameras. The new lingWAVES 4 HSV camera is super lightweight – with a weight of only 270g (0.59 lbs) it is the most smart camera available on the market, easy to hold in a hand.
New Thunderbold 3 (TB3) streaming technology enables long term recording.
This new camera uses streaming technology: In the past HSV cameras stored captured pictures within the memory of the camera with hardly 4 seconds recording time. Today we use Thunderbold 3 streaming for a direct and real-time transfer of pictures to the computer memory. This enables customers to record 60 seconds and more – in high speed.
And the whole procedure starting from taking the video from a client, doing a report and saving data takes less than 10 minutes – a new time dimension in this field (in the past it took at least 45 – 90 minutes)
lingWAVES 4 HSV comes complete with a ready-to-run powerful workstation notebook and a modern LED light source for perfect illumination combined with an optimized rigid endoscope.
Camera and Light Source Specifications
Our high speed camera has a maximum resolution of 1.440 x 1.024 pixel – color. Full lens rigid endoscopy recordings are made at 4.000 fps. Higher frame rates are possible at lower resolution up to 8.500 fps.
A powerful LED light source is part of lingWAVES 4 HSV with long life LEDs and light power regulation.
