Ultrasound-based radial and longitudinal strain estimation of the carotid artery: a feasibility study

IEEE Trans Ultrason Ferroelectr Freq Control. 2011 Oct;58(10):2244-51. doi: 10.1109/TUFFC.2011.2074.

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.
