提供了用于处理使用超声弹性成像获取的数据的系统和方法，在所述系统和方法中，使用超声换能器的持续振动在对象中生成剪切波。在此描述的系统和方法可以有效地去除与所述超声换能器的振动相关联的运动伪影，并且还可以去除逐行成像模式用于获取数据(如许多常规超声扫描器完成的那样)时所造成的数据采样未对准。因此，在此描述的系统和方法提供用于换能器运动校正以及用于对准由逐行扫描超声系统检测到的运动信号的技术。 Systems and methods for processing data acquired using ultrasound elastography, in which shear waves are generated in a subject using continuous vibration of an ultrasound transducer, are provided. The systems and methods described here can effectively remove motion artifacts associated with vibration of the ultrasound transducer, and can also remove the data sampling misalignment caused when a line-by-line imaging mode is used to acquire data, as is done by many conventional ultrasound scanners. Thus, the systems and methods described here provide techniques for transducer motion correction and for aligning motion signals detected by line-by-line scanning ultrasound systems.
