Specific Vocal Fold Vibration Patterns Seen In Accumulative Lesions. Analysis by High-Speed Digital Imaging.

Quantification of Vocal Fold Vibration in Various Laryngeal Disorders Using High-Speed Digital Imaging.

OBJECTIVE To quantify vibratory characteristics of various laryngeal disorders seen by high-speed digital imaging (HSDI). METHODS HSDI was performed on 78 patients with various laryngeal disorders (20 with polyp, 16 with carcinoma, 13 with leukoplakia, 6 with vocal fold nodule, and 33 with others) and 29 vocally healthy subjects. Obtained data were quantitatively evaluated by frame-by-frame a...

Vocal-fold vibration of patients with Reinke's edema observed using high-speed digital imaging.

OBJECTIVE We aimed to assess the vocal-fold vibration of patients with moderate-to-severe Reinke's edema using high-speed digital imaging (HSDI) and videostroboscopy and to confirm HSDI usefulness in examining the vocal folds with Reinke's edema. METHODS We examined the vocal folds of seven patients (six severe and one moderate; six females and one male; aged 55-74 years; mean 64.7 years) wit...

A novel high-speed digital imaging system for assessing vocal fold vibration

High-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...
