超声弹性成像中应变滤波器的理论及其发展

弹性成像能够提供组织弹性这一基本的力学属性,具有很广阔的应用前景。应变滤波器是超声弹性成像的重要理论框架,可广泛应用于超声弹性成像效果的评估、分析和预测。本文详细综述了应变滤波器的理论和发展,并对文献中的一些笔误作了修正,对实现的一些细节作了说明。通过对应变滤波器的理解,可以加深对超声弹性成像效果的理解,并对采用合适的方法和参数以获得最佳的成像效果以指导。

The theory and development of the strain filter in ultrasound elastography

Elastography can provide the intrinsic mechanical property of tissue elasticity,and hence has wide prospects.The strain filter is an important theoretical framework for ultrasound elastography.In this paper,the theory and development of the strain filter is reviewed in detail,as well as some clerical errors in literatures.The understanding of ultrasound elastography,can deepen our understanding of the effects on ultrasound elasto g-raphy,and guide us to se lect ap plicable meth ods and param eters to achieve the best performance.
