碩士 === 國立臺灣科技大學 === 高分子系 === 98 === Strobo-Laryngoscope is a useful and assistant instrument for clinical diagnosis of vocal folds. Professional physicians interpret vocal folds imaging and make the diagnosis appropriate for the imaging. However, measuring vocal folds dimensions such as length, area, perimeter and angle, etc. in absolute quantities has been difficult, because the distance from the larynx to the tip of the endoscopy is varied. Therefore, there is no standard reference for calibrating endoscopic images. This study deals with the optical effect of endoscopy, the laser projection marking module is designed and integrated on endoscopy to provide a reference for scale transformation. Furthermore, this paper presents the digital image process technique to recognize vocal folds from endoscopy images, carried out on the extraction of objective parameters, which help to express a diagnosis more intuition and robust than the directly observation of images. An effort can assist physicians in assessing imaging, help to reduce the medical resources consumed and improve the efficiency of diagnosis. Finally, this study applied to 40 healthy voice subjects and established database of vocal parameters based on laser projection marking module and image process. This database enables accurate quantitative morphological measurement within the vocal folds that could be used even in clinical routine and helps to reduce the subjective judgments and opinions, and enhance the quality of medical treatment.
