动脉壁的局部弹性性质是诊断动脉粥样硬化的有用标志，因为动脉粥样硬化病变是局部形成的。脉搏波传导速度是评价动脉壁弹性的无创性指标。然而，动脉壁运动的测量需要高的时间分辨率，因为脉搏波以每秒几米的速度沿动脉沿着传播。在本研究中，动脉壁运动测量在一个高的时间分辨率在1302帧每秒（fps）使用平面波超快超声。另外，为了确定沿动脉沿着约20 mm的短段中的局部脉搏波速度，开发了估计脉搏波的时间和空间频率的方法。通过仿真实验验证了该方法的准确性，并将其应用于人体颈动脉的活体测量。
The regional elastic property of the arterial wall is a useful marker for the diagnosis of atherosclerosis because an atherosclerotic lesion is formed locally. Pulse wave velocity is a noninvasive index for the evaluation of the elasticity of the arterial wall. However, a high temporal resolution is required for the measurement of the arterial wall motion because the pulse wave propagates along the artery at several meters per second. In the present study, the arterial wall motion was measured at a high temporal resolution at 1302 frames per second (fps) using plane-wave ultrafast ultrasound. Also, a method of estimating the temporal and spatial frequencies of the pulse wave was developed for the determination of the regional pulse wave velocity in a short segment of about 20 mm along the artery. The accuracy of the proposed method was evaluated by simulation experiments and its feasibility was examined in the in vivo measurement of the human carotid artery.
