Depth kymography
Depth-kymography is the 3D display of the human
vocal fold vibrations by measuring their vertical and horizontal movements simultaneously, using a specially designed 3D endoscope. This 3D imaging method and the scientific term "Depth-Kymography" were introduced by Dr. Nibu A George, Prof. Frits de Mul and Prof. Harm Schutte. [1] [2] from the University Medical Center Groningen, The Netherlands in 2007. The term "Depth-Kymography" is included in the current medical terminology
.
Human vocal folds vibrate in a very complex manner. During
Laryngoscopes. With a specially designed 3D laryngoscope, movement of the vocal folds in the horizontal and the vertical directions can be simultaneously measured and displayed with horizontal and vertical displacements, forming the two orthogonal planes with time as the third dimension. Using this method, researchers were also able to measure the mucosal wave propagation. Depth-kymography has great potential in the investigation of voice disorders and in phonosurgical applications. It is the next generation of the popular videokymography.[3]
