Progress in atherosclerotic plaque imaging

Figure 9 In vitro intravascular echogram and elastogram of a human femoral artery. The elastogram reveals that the plaque at 12 o’clock contains a soft core that is covered from the lumen by a stiff cap. At 9 o’clock a soft tissue is present at the lumen vessel-wall boundary. A different strain was found at 9 and 3 o’clock and this difference was not present in the echogram[140].
