Layer-Dependent Variation in the Anisotropy of Apparent Integrated Backscatter from Human Coronary Arteries
2011, Ultrasound in Medicine and BiologyCitation Excerpt :Picano et al. (1985) observed some differences in angle dependence among plaque types in studies of excised aortas. De Kroon and collaborators examined the backscatter from excised iliac arteries as a function of angle (de Kroon et al. 1991a, 1991b). These authors observed layer-dependent variation with angle, although the experimental apparatus permitted only modest departures from the perpendicular to the vessel surface.
Physical Properties of Tissues Relevant to Arterial Ultrasound Imaging and Blood Velocity Measurement
2007, Ultrasound in Medicine and BiologyCitation Excerpt :It has been recognized that IBS is dependent on machine factors, making it difficult to compare IBS measured using different machines (Ota et al. 1997), and that assumed values for attenuation of overlying tissues will affect estimated IBS (Bridal et al. 1998). Measurements in excised arteries have demonstrated higher backscatter in calcified and fibrous plaque compared with normal arteries or fatty plaque (Wickline 1993; Barzali et al. 1987; Bridal et al. 1998; Takiuchi et al. 2000; Waters et al. 2003) and anisotropic behavior with higher IBS in the radial orientation (Nguyen et al. 2002; de Kroon et al. 1991a). More complex techniques aimed at differentiating tissue types have been published (Spencer et al. 1997; Komiyama et al. 2000; Watson et al. 2000; Nair et al. 2002), but these are developed on the basis of discrimination between tissues, not on the basis of estimation of physical properties.
