Objective To evaluate the probable effects of different instrumentation in velocity measurements and the correlations between the actual flow velocities and the Doppler flow velocity.
目的探讨不同彩色多普勒超声诊断仪对流速测定的可能影响，以及不同仪器测定流速与实际流速的差异和相关性。
Conclusions the Doppler flow velocities and the actual flow velocities have significant correlations, which provides Doppler flow image as an effective method to evaluate hemodynamics.
结论多普勒测量的流速与实际流速之间有很好的相关性，是评价血流动力学的有效手段。
