“…Scatterers not belonging to the artery lumen in a static map (diameter D 0 = 5 mm) were then selected, and longitudinal displacement d longitudinal ( f 1 ) in the X–Z plane was added to each scatterer. Other studies [ 33 , 34 ] have demonstrated that the intima–media complex shows a larger longitudinal motion than the adventitia layer. Therefore, for scatterers that were outside the intima–media complex (i.e., adventitia layer and surrounding tissues), longitudinal displacement was added with sloping according to distance from the artery center (see Figure 7 ): where y is the radial position as the absolute radial distance from the artery axis, r l = 2.5 mm is the lumen radius, r ma = 3.2 mm is the radius of the media-adventitia boundary, b 2 = 1.08 expresses the slope of the longitudinal displacement and was chosen the same as proposed by Stoitsis et al [ 23 ];…”
