非均匀软组织的低频位移或应变可作为活体组织内部的动态可视化触诊，直接应用于临床诊断。然而，对于这种动态成像，组织横截面上的横向位移应通过使用传统的B模式阵列换能器以优异的精度进行评估。利用压缩到1比特的二维复回波信号实现了小位移估计。通过对真实的实时采集的射频回波帧进行连续处理，实现了二维应变的动态成像。
The displacement or strain at low frequency in an inhomogeneous soft tissue could be directly applied to clinical diagnosis as a dynamic visualized palpation for internal living tissues. However, for this dynamical imaging the lateral displacement on tissue cross section should be evaluated with excellent accuracy by using a conventional B-mode array transducer. By using 2-dimensional complex echo signals which are compressed to 1-bit this small displacement estimation was realized. Furthermore, by successively processing the rf echo frames that are taken at real time, dynamic imaging of 2-dimensional strain was realized.
