摘要
心脏超声检查对于心脏疾病的诊断起到至关重要的作用。心脏复杂的血流动力学需要更高级的超声成像模式。心脏超声向量血流成像可以直接获得血流速度的实际大小和方向,从而获取更多的血流动力学定量参数,为临床研究与诊断提供更多信息。主要回顾了几种心脏向量血流技术及其实现难点,并提出一种基于发散波的高帧率心脏超声向量血流成像。讨论了当前各种超声成像技术在心脏血流测量领域中的局限,分析并阐明了造成这些难题的具体原因和未来的发展方向。
Echocardiogram is vital for the diagnosis of cardiac disease.The heart has complex hemodynamics requiring an advanced ultrasound imaging mode.Cardiac ultrasound vector flow imaging is capable of measuring the actual magnitude and direction of the blood flow velocity,obtaining the quantitative parameters of hemodynamics,and then providing more information for clinical research and diagnosis.This study mainly reviewed several different vector flow imaging techniques for cardiac flow and presented the implementation difficulties,and proposed a diverging wave based high frame rate cardiac ultrasound vector flow imaging.The study discussed the limitation of current ultrasound technology used in the cardiac flow measurement,analyzed and demonstrated the specific reasons for these implementation difficulties and the potential future development.
