The Doppler technique has traditionally been the method used to extract motion information from ultrasonic echoes reflected by moving tissues. The Doppler technique has been around for a long time, and has been extensively reviewed and analyzed in the literature. Recently, time-domain methodologies for estimating tissue motion have gained in popularity. Time-domain methods have advantages over Doppler methods in many applications, and as of yet have not been comprehensively reviewed. An overview of time-domain techniques that have appeared in the literature over the past few years is presented. Their potential advantages over Doppler are examined, and the individual techniques are compared.
传统上，多普勒技术一直是用于从移动组织反射的超声回波中提取运动信息的方法。多普勒技术已经存在了很长时间，并且在文献中已经得到了广泛的综述和分析。最近，用于估计组织运动的时域方法越来越受欢迎。时域方法在许多应用中比多普勒方法具有优势，并且迄今为止尚未得到全面的综述。本文概述了过去几年文献中出现的时域技术。研究了它们相对于多普勒技术的潜在优势，并对各种技术进行了比较。
