In order to investigate the vibration pattern, especially the vibrational phase of tissue beneath the vocal fold mucosa, an imaging method called electroglottogram-triggered ultrasonography is proposed. The ultrasonic images of the vocal fold vibration are obtained in the coronal plane from five adult subjects during phonation. The velocity of the vocal fold tissue beneath the mucosal surface is obtained by using a motion estimation method. The results show that the vibration phase difference between tissues at different locations beneath the vocal fold mucosa results in a mechanical wave traveling upward at a speed of 720 to 1826 mm/s.
为了研究振动模式，特别是声带黏膜下组织的振动相位，提出了一种称为声门图触发超声的成像方法。在发声期间，从五个成年受试者中获得了冠状平面的声带振动超声图像。通过运动估计方法获得了粘膜表面下方声带组织的速度。结果表明，声带粘膜下不同位置组织的振动相位差导致机械波以 720 至 1826mm/s 的速度向上传播。
