Spectral tissue strain: A new technique for imaging tissue strain using intravascular ultrasound

Inflation and Bi-Axial Tensile Testing of Healthy Porcine Carotid Arteries

“…Both can be measured with ultrasound (strain) imaging techniques, either in vivo or using the in vitro inflation method (Boekhoven et al 2014;Hansen et al 2013;. From the radiofrequency (RF) data, local deformation fields are estimated and displayed as color overlays on the regular B-mode images, that is, strain imaging (Talhami et al 1994). The combination of inflation testing and ultrasound strain imaging has been used in healthy and atherosclerotic tissue (Boekhoven et al 2013;Ribbers et al 2007) and in other types of arteries, mostly in a quasi-static fashion (Brusseau et al 2001;de Korte et al 1998;Lopata et al 2014;Schaar et al 2003).…”

Measurement of the transverse strain tensor in the coronary arterial wall from clinical intravascular ultrasound images

“…Since then, intravascular applications have been developed (Brusseau et al, 2001;de Korte et al, 1997;Ryan and Foster, 1997;Shapo et al, 1996;Talhami et al, 1994;Wan et al, 2001). de Korte et al de Korte et al, 1997) have used IVUS elastography to obtain vascular elastic properties; they measure radial strain by correlation analysis of RF signals recorded under different luminal pressures.…”

Estimation of the Transverse Strain Tensor in the Arterial Wall Using IVUS Image Registration

“…Various methods have been proposed to obtain the radial strain in the vessel wall from IVUS signals using 1-D cross-correlation techniques (Brusseau et al 2001;de Korte et al 1997ade Korte et al , 1997bTalhami et al 1994). de Korte and his colleagues have made significant contributions (de Korte et al 2002b;Schaar et al 2003).…”
