Abstract
Ultrasound-based estimation of arterial wall elasticity is commonly used to assess arterial stiffness. However, previous elastography studies have mostly addressed radial strain measurements, and the longitudinal strain has been more or less ignored. This study shows the feasibility of a speckle-tracking-based algorithm for simultaneous estimation of radial and longitudinal strain in the carotid artery in silico. Additionally, these results were preliminarily confirmed in vivo.
摘要
基于超声的动脉壁弹性估计常用于评估动脉僵硬度。然而，以前的弹性成像研究大多集中在径向应变测量上，或多或少忽略了纵向应变。本研究展示了一种基于散斑跟踪的算法在模拟中同时估计颈动脉径向和纵向应变的可行性。此外，这些结果在体内初步得到了验证。
