在过去的几年里，人们越来越关注使用超声的辐射力来评估、表征和成像生物组织。特别感兴趣的是那些在低频下测量组织的动态特性的方法。本文提出了一种新的组织探测方法--动态辐射力法，讨论了该领域中几种方法的相互关系，并比较了它们的特点。该领域的技术可以分为三类：瞬态方法。剪切波测量方法和最近开发的称为振动声成像的方法。最后一种方法是本文的重点。在简要描述前两种方法的关键概念后，我们将详细描述振动声成像。最后，我们将比较这些方法的能力和局限性。
Over the past few years there has been an increasing interest in using the radiation force of ultrasound for evaluating, characterizing and imaging biological tissues. Of particular interest are those methods that measure the dynamic properties of tissue at low frequencies. In this paper we present dynamic radiation force methods for probing tissue as a new held, discuss the inter-relationship of several methods within this field and compare their features. The techniques in this field can be categorized into three groups: transient methods. shear-wave measurement methods and a recently developed method called vibro-acoustography. The last method is the focus of this paper. After briefly describing the key concepts of the first two methods, we will present a detailed description of vibro-acoustography. Finally, we will compare the capabilities and limitations of these methods.
