我们提出了一种连续激发横波的定量横波成像技术。利用通用超声成像系统，通过彩色血流成像直接观察剪切波波前。在这项研究中，所提出的方法被应用到体内实验中，剪切波地图，即剪切波相位图，它显示了剪切波传播的介质内，剪切波速度图，观察到的骨骼肌在肩膀上。为了激发肩部骨骼肌内部的剪切波，采用了一种将小型振子与超声波探头相结合的混合式超声波换能器。用该方法测得冈上肌的剪切波速度为4.11 ± 0.06m/s（N = 4）。该值与声辐射力冲量法所得结果一致。
We have proposed a quantitative shear wave imaging technique for continuous shear wave excitation. Shear wave wavefront is observed directly by color flow imaging using a general-purpose ultrasonic imaging system. In this study, the proposed method is applied to experiments in vivo, and shear wave maps, namely, the shear wave phase map, which shows the shear wave propagation inside the medium, and the shear wave velocity map, are observed for the skeletal muscle in the shoulder. To excite the shear wave inside the skeletal muscle of the shoulder, a hybrid ultrasonic wave transducer, which combines a small vibrator with an ultrasonic wave probe, is adopted. The shear wave velocity of supraspinatus muscle, which is measured by the proposed method, is 4.11 ± 0.06 m/s (N = 4). This value is consistent with those obtained by the acoustic radiation force impulse method.
