Definitions
- the present invention relates to a planar scan videochimography image generation technique using ultrafast laryngoscope images. More particularly, the present invention relates to a planar scan video chimography image capable of analyzing the movement of the entire vocal cord mucosa from the ultrafast laryngoscope image.
- the present invention relates to a planar scan video chimography image generating method using a real-time or prestored ultra-fast laryngeal endoscope image to be stored or output to a display device, a planar scan video chimography image generating server performing the same, and a recording medium storing the same.
- the vocal fold of the human body is a vocal organ for communication via language, which causes the laryngeal mucosa to vibrate about 100 to 250 times per second along the breath. That is, the air sucked into the lower airway presses on the vocal cords that are closed in the sub-glottal area, and when the pressure becomes greater than the resistance of the vocal cords, it moves from the inferior margin to the superior margin of the vocal cords. Mucous waves form, the vocal cords open, and vocalization begins. When the pressure drops again, the vocal cords are closed and the voice is produced by repeating it 100 to 250 times per second.
