剪切波速度测量是一种很有前途的评价组织硬度的方法。目前已有多种方法测量剪切波速度，但低成本的系统难以实时获得定量的剪切波图像。本文提出了一种新的连续横波成像方法。该方法利用超声成像系统中的彩色血流成像技术获得剪切波的波前图。剪切波频率条件和剪切波位移幅值条件是计算剪切波位移的两个必要条件，但这些条件在大多数应用中并不严格。利用所提出的方法，测量了肌肉的剪切波速度。结果与用ARFI法测得的剪切弹性模量计算的速度一致。
Shear wave velocity measurement is a promising method in evaluation of tissue stiffness. Several methods have been developed to measure the shear wave velocity, however, it is difficult to obtain quantitative shear wave image in real-time by low cost system. In this paper, a novel shear wave imaging method for continuous shear wave is proposed. This method uses a color flow imaging which is used in ultrasonic imaging system to obtain shear wave's wavefront map. Two conditions, shear wave frequency condition and shear wave displacement amplitude condition, are required, however, these conditions are not severe restrictions in most applications. Using the proposed method, shear wave velocity of trapezius muscle is measured. The result is consistent with the velocity which is calculated from shear elastic modulus measured by ARFI method.
