速度向量成像(VVI)技术是新近出现的可不受角度限制定量检测局部组织生物力学特征的超声新技术。目前该技术多用于心血管结构力学的检测,并已取得较好的应用效果。文中就VVI技术在心血管研究中的应用作一综述。 Velocity Vector Imaging (VVI) is a new ultrasound technique that has recently emerged that can quantitatively detect the biomechanical characteristics of the local tissue without angle limitations. At present, the technology is mostly used for the detection of cardiovascular structural mechanics and has achieved good results. The article reviews the application of VVI technology in cardiovascular research.
