摘要： Acquire color Doppler data; detect one or more transition of the color Doppler data, each of the one or more transitions being between a first area representing flow velocity in a first direction and a second area representing flow velocity not in the first direction. Apply a first set of aliasing corrections to generate second color Doppler data, calculate a first energy function based on the one or more pairs of color Doppler values in the second color Doppler data which are located on opposite sides of the transition, and determine a first total energy function. Next, Apply a second set of aliasing corrections to generate third color Doppler data, calculate a second energy function based on the one or more pairs of color Doppler values in the third color Doppler data which are located on opposite sides of the transition, and determine a second total energy function.

摘要： The maximum frequency in a Doppler spectrum is obtained and used as an aliasing detector. When aliasing occurs, frequencies greater than a frequency limit change from one frequency region to another. When aliasing is detected, a zero frequency baseline is shifted to prevent future aliasing.

摘要： Blood flow information is used to reduce noise manifest in blood vessel ultrasound B-mode images. A blood flow signal is obtained by a flow detector. After high-pass filtering, only the flow signal power in the blood vessel lumen remains, while signal power from stationary tissue region is suppressed. The flow signal component is used to calculate a flow component parameter that is used to generate a gain control signal a that reduces noise in a B-mode image.
