“…Some of these features cannot be perceived without special tools, such as kymography. Several new image processing techniques [7,8,[10][11][12][13][14][15] allow for the registration and objective measurement of vocal fold features. However, the questions of selecting the most representative segments for applying these techniques, demonstrating their validity and reliability, and making them intuitive for clinical application, remain open.…”

“…Therefore, HSV by default overcomes the above limitations of stroboscopy and VKG providing for the possibility of more accurate objective quantification of the vocal fold vibratory behavior. Moreover, the existing duality between HSV and DKG [7,8] makes HSV uniquely suited for either spatial or kymographic representation of the same content. It is important to note that high-speed motion films have been used for studying the motion of the vocal folds [9] long before the development of commercial systems for laryngeal videostroboscopy.…”

“…Mittels HG-Aufnahmeserien lassen sich die von Titze vorhergesagten Kategorien von Irregularitäten unterscheiden: Seitendifferenzen entsprechen einer Rechts-links-Asymmetrie [27,15], und Schwingungen in Längsrichtung der Stimmlippen entsprechen einer dorso-ventralen Asymmetrie [29].…”

“…Die hier beschriebene digitale Kymographie hat gegenüber den eindimensionalen Vorläufern einen großen Vorteil: sie kann als Mehrlinien-Kymographie an mehreren Querschnittslinien der Glottis gleichzeitig berechnet werden [29,37] und damit auch Bewegungsabläufe erfassen, die an verschiedenen Stellen der Glottis unterschiedlich ablaufen. Solche Schwingungsmoden, die sich in dorsoventraler Richtung über die Stimmlippen ausbreiten,heißen "Longitudinal-" oder "ap-Moden".…”

“…Mittels HGG-Aufnahmeserien und Modellierung lassen sich 2 Kategorien von Irregularitäten unterscheiden: Seitendifferenzen kann man in der Orientierung des Bildschirms als "horizontale" Asymmetrie bezeichnen [27], und Schwingungen in Längsrichtung der Stimmlippen als "vertikale" [29].…”
