已经开发并证明了一种能够确定复杂血液速度的幅度和方向的超声多普勒系统。该系统使用一个发射机和两个接收机来分辨正交速度矢量分量。该系统已在一个移动的字符串体模和颈动脉上进行了测试。该方法可以改善早期血管疾病的检测，并提高外周动脉中的体积血流测量的准确性。
An ultrasound Doppler system capable of determining both the magnitude and direction of complex blood velocities has been developed and demonstrated. This system uses a single transmitter and two receivers to resolve orthogonal velocity vector components. The system has been tested on a moving string phantom and on a carotid artery. The method may improve the detection of early vascular diseases and improve the accuracy of volumetric blood flow measurements in peripheral arteries.
