A new computer-analyzing system for clinical use with a strobo-videoscope.
We introduce a new method for using the computer-analyzing system that deals with a display on a television screen of moving picture frames of the vibrations of vocal folds taken by a stroboscopic videoscope in various voice disorders. The principle of the analyzing system is based on discrimination between the first and second videoscopic images by means of the different intensities of colors. We describe the usefulness of this system in measuring the excursion of the right and left vocal folds, where the glottal transverse diameter and the glottal area are computed and displayed as a function of time.
