Effects of Vocal Fold Nodules on Glottal Cycle Measurements Derived from High-Speed Videoendoscopy in Children.
The goal of this study is to quantify the effects of vocal fold nodules on vibratory motion in children using high-speed videoendoscopy. Differences in vibratory motion were evaluated in 20 children with vocal fold nodules (5-11 years) and 20 age and gender matched typically developing children (5-11 years) during sustained phonation at typical pitch and loudness. Normalized kinematic features ...
متن کاملHigh-Speed Smart Camera with High Resolution
High-speed video cameras are powerful tools for investigating for instance the biomechanics analysis or the movements of mechanical parts in manufacturing processes. In the past years, the use of CMOS sensors instead of CCDs has enabled the development of high-speed video cameras offering digital outputs, readout flexibility, and lower manufacturing costs. In this paper, we propose a high-speed...
متن کاملThe VHI Analysis of vocal polyps and vocal nodules
Objective: Explore the practical clinical significance and correlation of voice handicap index (VHI) for vocal polyps and vocal nodules, and further validate practicality of VHI. Methods: VHI of vocal cord polyp group (n = 35), vocal nodule group (n = 29), and control group (n = 22) was surveyed respectively. The VHI investigation included three categories of function (F), physiology (P) and em...
متن کاملImprovement of Vocal Pathologies Diagnosis Using High-Speed Videolaryngoscopy
Introduction The study of the dynamic properties of vocal fold vibration is important for understanding the vocal production mechanism and the impact of organic and functional changes. The advent of high-speed videolaryngoscopy (HSV) has provided the possibility of seeing the real cycle of vocal fold vibration in detail through high sampling rate of successive frames and adequate spatial resolu...
متن کاملHigh-speed Laryngeal Imaging Analysis of Vocal Fold Dynamics
High-speed laryngeal Imaging (HSLI) provides a direct means to observe the actual vibration of the vocal folds and allows for comprehensive analyses of vocal fold dynamics in normal and abnormal voice productions. Glottal edge detection is a key operation for tracing vibrations of the vocal folds at spatial locations and obtaining glottal area waveform (GAW) from the HSLI data. We have develope...
