Imaging of vocal fold vibration by digital multi-plane kymography

Digital multi-plane kymography is presented as a new method to demonstrate vocal fold vibration from digital high-speed recordings. Single lines from digital high-speed sequences of laryngoscopical examinations are concatenated to images, which are called kymograms. In order to reveal anterior-poste...

Description
Summary:Digital multi-plane kymography is presented as a new method to demonstrate vocal fold vibration from digital high-speed recordings. Single lines from digital high-speed sequences of laryngoscopical examinations are concatenated to images, which are called kymograms. In order to reveal anterior-posterior (AP) modes of vibration several kymograms from different location of the glottis can be obtained from a single recording. Problems due to rotation of the endoscope or relative movements of patient or examiner can be solved by image processing algorithms specifically designed for this application. Different types of phonation onset and examples of voice disorders are given.
