[Design and improvement of stenosis model in cylindrical tubal flow via pulsed Doppler ultrasound in vitro].
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.
