Abstract
Purpose: The aim of this study was to establish a method to observe vocal fold vibration using a low-cost high-speed laryngeal imaging system. Procedures: We assembled a high-speed imaging system with a consumer digital camera and a rigid laryngeal endoscope. The camera can shoot digital images at a rate of 1,200 frames per second and be purchased for about USD 1,000 in Japan. Results: We examined the normal and pathological vocal folds of 215 subjects with our new system and analyzed the vocal fold vibration in these subjects by playback of a video and kymograph images. Conclusions: Our high-speed laryngeal imaging system is highly cost-effective and can be a useful tool for examining the vocal folds of patients with voice disorders.
