摘要:本文提出了一种利用单片机进行控制,结合电声门图仪和全数字化超声系统,共同完成声带振动特定相位观测的动态成像系统。该系统利用外围硬件电路对电声门图信号的特征相位点进行识别,并通过单片机对图像采集时刻进行精确的计算和控制,可以完成声带振动频率的测量,声带静态相位的持续观测和声带振动过程的动态慢放。通过搭建实验系统进行系统测试,验证了方法的可靠性和有效性,并最终实现了此动态成像系统对声带振动过程的实时观测。

Controllable Dynamic Ultrasound Imaging System of Vocal Fold Vibration Based on Electric Glottis Graph
Abstract:In this paper, a dynamic imaging system controlled by single chip microcomputer is presented. This system combines electric glottis graph signal and ultrasonic imaging, in order to get the special phase imaging of vocal fold vibration. It can identify the special phase of electric glottis graph with the help of hardware circuit and then it uses the single chip microcomputer to control the trigger pulse, so as to get the frequency of vocal fold vibration, static and dynamic imaging of vocal fold vibration. Finally, comprehensive experiments validate the feasibility and effectiveness of the proposed method. In addition, the dynamic ultrasound imaging system can observe the vocal fold vibration clearly.
Keywords: ultrasonic imaging vocal fold vibration single chip microcomputer control
