The rupture of atherosclerotic plaque leads to serious events, such as cerebral infarction and stroke. Therefore, it is important to assess the arterial dynamics to evaluate the vulnerability of plaque. In this study, methods for measurement of the arterial dynamics, such as accurate measurement of 2-dimensional motion of the arterial wall and a new method for imaging blood flow at a very high frame rate of 3500 Hz, have been developed.

动脉粥样硬化斑块破裂会导致严重的事件，如脑梗塞和中风。因此，评估动脉动力学对评估斑块的易损性具有重要意义。在这项研究中，已经发展了测量动脉动力学的方法，如精确测量动脉壁的二维运动和在3500赫兹的极高帧速率下成像血流的新方法。
