A receive beam-tracking technique is introduced for simultaneously measuring more than one dimension of an existing velocity vector in medical ultrasound. By using flexible beamforming and a conventional linear-array transducer, vectors can be measured at real-time frame rates over a significant field of view. Both simulations and in vitro experiments show that this technique should provide more accurate measurements of blood flow velocities in the human body than is available with current color flow mapping systems.
本文介绍了一种接收波束跟踪技术，用于在医学超声中同时测量现有速度矢量的多个维度。通过使用灵活的波束形成和传统的线性阵列换能器，可以在较大的视野范围内以实时帧率测量矢量。模拟和体外实验均表明，与当前的彩色血流映射系统相比，该技术应能提供更准确的人体血流速度测量结果。
