摘要
建立和改进了体外圆管流动的急剧狭窄模型。借助商品化临床使用脉冲多普勒超声技术探讨了流动指标的检测方法。在狭窄前后多个位点进行多时点检测 ,并得出流场特征 ,通过不同指标分别刻划狭窄前后流场。
A model of disturbed flow downstream of a severe stenosis has been established and improved in vitro, and the relevant method and feasibility for the detection of flow indices are discussed via commercially available Pulsed Doppler Ultrasound (PDU). Detection is done temporally and spatially, upstream and downstream. The methodology is proved to be feasible and has good prosperity of clinical use.
