| Research Abstract |
Vocal folds vibration has important role for speech production. To observe and analyze the dynamic aspects of the vocal fold vibration, we applied high speed cine-MRI method. In this study, we examined following: (i) We developed MRI larynx coil to obtain the MR images of vocal folds. (ii) High speed cine-MRI method was improved. (iii) Dynamic aspects of the tongue vibration producing tongue trill sound was captured as cine-MRI by using the method. (iv). This method was applied to the speaker who producing speech sounds. The images were clearer than that derived by using conventional cine-MRI technique. (v) The closing and opening the vocal folds were captured by the method. This study indicate the points to improve the image quality of the cine-MRI.
