Accurate Measurement of Arterial Dynamics by High Frame Rate Ultrasonic Imaging

动脉粥样硬化斑块的破裂导致严重的事件，如脑梗死和中风。因此，动脉动力学的评价对评价斑块的易损性具有重要意义。在这项研究中，用于测量动脉动力学的方法，如精确测量动脉壁的二维运动和一种新的方法，用于成像血流在一个非常高的帧速率为3500 Hz，已经开发。

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.
