The Restriction Between Distance and Velocity Measurement in Medical Doppler Ultrasound and the Detection of Blood Flow Velocity Profile / 中华超声影像学杂志

The restriction between distance and velocity measurement in medical Doppler ultra-sound is first proposed in this paper.The reasons resulting in this restriction are also analysed.Then our method to estimate blood flow velocity profile is introduced,in which the restriction is avoided.The discussion of this restriction in medical Doppler ultrasound and the method to detect blood flow velocity profile are finally presented.
