Clinical implementation of laryngeal high-speed videoendoscopy: challenges and evolution.
High-speed videoendoscopy (HSV) captures the true intracycle vibratory behavior of the vocal folds, which allows for overcoming the limitations of videostroboscopy for more accurate objective quantification methods. However, the commercial HSV systems have not gained widespread clinical adoption because of remaining technical and methodological limitations and an associated lack of information ...
متن کاملLaryngeal High-Speed Videoendoscopy: Sensitivity of Objective Parameters towards Recording Frame Rate
The current use of laryngeal high-speed videoendoscopy in clinic settings involves subjective visual assessment of vocal fold vibratory characteristics. However, objective quantification of vocal fold vibrations for evidence-based diagnosis and therapy is desired, and objective parameters assessing laryngeal dynamics have therefore been suggested. This study investigated the sensitivity of the ...
متن کاملFast FFT-based motion compensation for laryngeal high-speed videoendoscopy
(HSV) are compared. Two of them are based on tracking the maximum of the cross-correlation function of two images; two are based on minimization of the L 2 –norm and L 2-like distance between two images ; and the other two make use of the peak present in the cross-power FFT-based spectrum of two images. All six methods are applied to compensate the motion, at the sub-pixel level, of the endosco...
متن کاملBiomechanical simulation of vocal fold dynamics in adults based on laryngeal high-speed videoendoscopy
MOTIVATION Human voice is generated in the larynx by the two oscillating vocal folds. Owing to the limited space and accessibility of the larynx, endoscopic investigation of the actual phonatory process in detail is challenging. Hence the biomechanics of the human phonatory process are still not yet fully understood. Therefore, we adapt a mathematical model of the vocal folds towards vocal fold...
متن کاملSegmentation of laryngeal high-speed videoendoscopy in temporal domain using paired active contours
(HSV). The method employs a pair of active contours (snakes), which deform within a series of kymographic images derived from the HSV data. By following a set of deformation rules, this pair of active contours converges to the desired boundaries of the glottis. The proposed method was tested on a dataset of 98 HSV samples, of which 96 were successfully segmented. The new method substantially ou...
