Study on the Detection Method of Hemodynamic Parametersin Different Stenosis

  • 摘要: 为研究不同狭窄度斑块的血液动力学参数——应力相位角, 利用高频超声成像系统采集不同狭窄度斑块的超声造影图像, 并通过超声粒子图像测速算法和互相关算法计算得到这一参数。结果显示, 30% 狭窄度斑块的平均应力相位角为 -162.88°;50% 狭窄度斑块的平均应力相位角为 -201.99°;70% 狭窄度斑块的平均应力相位角为 -222.89°。该研究表明, 斑块狭窄程度越大, 应力相位角的数值越负, 壁面剪切力和周向应力越不同步。
    Abstract: To investigate the hemodynamics parameter of stress phase angle (SPA) in different stenosis states, the high-frequency ultrasonic imaging system was employed to obtain ultrasound contrast images of stenotic plaques, and the value of SPA was calculated through echo particle image velocimetry and cross-correlation algorithms. The experimental results showed that when the stenosis was 30%, 50% and 70%, the mean SPA was -162.88°, -201.99° and -222.89°, respectively. The study may suggest that the bigger stenosis, the more negative the SPA and the more asynchronous between the wall shear stress and circumferential stress.
