1. A 2D scanning videokymography system for analyzing a vibration of vocal-fold mucosa, comprising:
a laryngoscope for observing vocal folds;
a light source for illuminating the vocal folds;
a video camera for recording and storing images observed through the laryngoscope;
a computer comprising an image capture unit for converting a video signal transmitted from the video camera into a digital image signal, a storage unit for storing the digital image signal, a control unit for analyzing the image signal of the storage unit and displaying the analysis results on a monitor, and analysis software for analyzing the image signal of the storage unit; and
a monitor for displaying a captured image and analysis results,
wherein the computer displays a normalized index including an average vocal-fold width for a longitudinal-axis length of a glottis, a glottis opening ratio which is a ratio of a vocal-fold opening period and a total period, an asymmetric index which is a difference in opening degree of both vocal folds, a basic frequency, a vibration strength, regularity of vibration, a mucosa wave, symmetricity of the vibration, an outer boundary shape, an inner boundary shape, an abnormal cycle, and vibration absence of the vocal-fold mucosa.
