论文摘要
医学超声波的主要主题取决于通过组织传播波的物理。这些包括反向散射，声音速度，衰减和斑点形成的基本治疗方法。每个主题都发展了自己的丰富历史，词典和特定的治疗方法。但是，有足够的证据表明，在与医学超声有关的所有基本现象中，权力法关系在基本层面上运行。这篇综述论文从过去60年中的文献中发展出了累积的理论基础和实验证据，这些证据表明了超声波和剪切波中最重要的组织波相互作用的力量行为，这些行为现在在弹性中使用。权力定律的常见框架可以作为对主题的连贯概述，也可以作为改善组织表征的一种手段。
Major topics in medical ultrasound rest on the physics of wave propagation through tissue. These include fundamental treatments of backscatter, speed of sound, attenuation, and speckle formation. Each topic has developed its own rich history, lexicography, and particular treatments. However, there is ample evidence to suggest that power law relations are operating at a fundamental level in all the basic phenomena related to medical ultrasound. This review paper develops, from literature over the past 60 years, the accumulating theoretical basis and experimental evidence that point to power law behaviors underlying the most important tissue-wave interactions in ultrasound and in shear waves which are now employed in elastography. The common framework of power laws can be useful as a coherent overview of topics, and as a means for improved tissue characterization.
