内容記述 | Observing vocal fold vibration is essential when investigating the causes of hoarseness of voice and determining the appropriate treatment. However, in Japan, it is difficult at present to obtain commercial high-speed digital imaging (HSDI) systems for this purpose because of a lack of marketing routes. Accordingly, we devised an HSDI system using a high-speed camera (monochrome HiSpec1). We chose this camera as it has been an established instrument in industrial and laboratory use; it also provided excellent light sensitivity, and used a 400-watt xenon light source for the acquisition of bright and clear images. The HSDI system enabled video capture of up to 4.4 s with our usual setting of 422 × 384 pixels at 3000 frames per second (fps). It can also capture videos in various settings such as 396 × 256 pixels at 4000 fps. In addition, we equipped the system with devices for concurrent audio waveform acquisition. Our novel laryngeal HSDI system could be a useful clinical tool for vocal fold examination in patients with voice problems when access to commercially available devices is limited. | |||||
