由于声带的双层组织结构，声带振动是一种覆盖身体的分层振动模式。提出了一种基于同步成像系统的声带体盖振动模式成像测量方法。该成像系统由两部分组成：高帧频超声成像部分和高速视频部分，可以对人体的振动和覆盖层进行高速同步成像。然后，应用图像分析方法从两个记录的图像序列中测量声带的体盖振动。在实验测量的基础上，分析了车身层振动的特性。此外，这些结果符合人体覆盖物模型的模拟。
Vibration of vocal folds is a body-cover layered vibration pattern due to the two-layer tissue structures of vocal folds. A method based on a synchronal imaging system is proposed in order to image and measure the body-cover vibration pattern of vocal folds. This imaging system contains two parts: high-frame-rate ultrasonic imaging part and high-speed video part, which can synchronously image the vibration of the body and cover layers at high speed. Then, image analysis methods are applied to measure the body-cover vibration of vocal folds from both recorded image sequences. We analyze characteristics of body-layer vibration based on the measurements from designed experiments. Moreover, these results meet simulations of a body-cover model.
