摘要:

本文研究了超声多角度平面波(Multi-angle Plane Wave,MPW)相干复合血流速度剖面(Blood Flow Velocity Profile,BFVP)检测的关键参数.基于Field II超声仿真平台开展仿真实验,分别建立水平、倾斜颈总动脉(Common Carotid Artery,CCA)平面波超声仿真模型.使用3~11个角度、间隔0.25°~16°的MPW扫描水平CCA生成复合图像,基于散斑跟踪法(Speckle Tracking,ST)测量BFVP;使用3个角度、间隔0.25°~20°的MPW扫描倾斜CCA生成复合回波信号,基于多普勒测速法(Doppler Velocimetry,DV)估计BFVP.对比预设理论速度剖面,ST法与DV法的最优参数分别为11个间隔1.0°、3个间隔3.0°的平面波.基于造影增强的兔髂动脉开展体内实验,验证了最优参数的有效性.综上所述,本文研究为MPW相干复合检测BFVP的参数设置提供参考,有助于获得准确的临床诊断信息.

Abstract:

Key parameters of the ultrasonic multi-angle plane wave(MPW) coherent compounding for the blood flow velocity profile(BFVP) detection are studied. Based on the ultrasonic simulator Field II, ultrasound plane-wave simulation models of the horizontal and inclined common carotid arteries(CCAs) are built. MPWs with the number of angles from 3 to 11 and the interval of angles from 0.25° to 16° are used to scan the horizontal CCA model to generate the compounded images, and the BFVPs are measured with the speckle tracking(ST) method. Three-angle plane waves with the interval from 0.25° to 20° are used to scan the inclined CCA model to acquire the compounded echo signals, and the BFVPs are measured with the Doppler velocimetry(DV). Compared with preset theoretical velocity profiles, the optimum parameters for the ST and DV methods are 11 plane waves with an interval of 1.0°, and 3 plane waves with an interval of 3.0°, respectively. Based on the enhanced rabbit iliac arteries with the contrast agents, the in-vivo experiments are implemented to demonstrate the effectiveness of the optimum parameters. In summary, this work provides a reference for the parameter configuration on the MPW coherent compounding for the BFVP detection, which is helpful to obtain the accurate diagnosis information in clinics.
