Videostroboscopy is a high-speed medical imaging method used to visualize the dynamics of human vocal fold vibration.
This process is called phonation and produces the sound of the human voice.
During phonation, the vocal folds open and close too rapidly for the unassisted eye to observe their movement.
This poses a problem to clinicians because abnormalities in these movements are often indicative of a voice disorder.
In the resulting stroboscopic video recording, the vocal folds appear slow enough to observe the precise nature of the movement, enabling the diagnosis of a range of problems.
