喉頭ストロボスコープKAYRLS-9100を主体としたコンピューター制御のビデオ内視鏡画像システム

抄録

A computer-integrated videostroboscope system (manufactured by the Kay Elemtrics Corporation) has been developed to visualize vocal fold vibration. The system consists of a KAY RLS-9100 laryngostroboscope, rigid laryngoendoscopes connected to a compact CCD color video camera, a display monitor, a video tape recorder (VTR), a digital color video printer and a specially programmed computer. It is technically simple to perform a videostroboscopic examination with this system, which was used to evaluate the vibratory pattern of the vocal folds in two female patients. This system provided distinct stroboscopic images and autosequence multiple images of both high quality and resolution of detail. The new system should be useful in diagnosing dysphonia.
