    • An ultrasound imaging system includes receive circuitry (110) configured to receive electrical signals from ultrasound transducer elements wherein the electrical signals are indicative of sensed ultrasound echo signals. The system further includes an image process (114) configured to process the electrical signals and generate a 2-D image. The system further includes a vessel wall identifier (116) configured to identify at least a proximal wall and a distal wall of a vessel in the B-mode image from the B-image employing a signal mirroring technique. The system further includes a rendering engine (124) configured to display the 2-D image on a display (126) with graphical indicia corresponding to the identified proximal wall and distal wall superimposed over the vessel in the 2-D image.

    • 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.
    • 获取彩色多普勒数据; 检测所述彩色多普勒数据的一个或多个转换,所述一个或多个转换中的每一个在代表第一方向上的流速的第一区域和表示不在所述第一方向上的流速的第二区域之间。 应用第一组混叠校正以产生第二彩色多普勒数据,基于位于该转换的相对侧的第二彩色多普勒数据中的一对或多对彩色多普勒值计算第一能量函数,并且确定第一 总能量功能。 接下来,应用第二组混叠校正以产生第三彩色多普勒数据,基于位于转换的相对侧的第三彩色多普勒数据中的一对或多对彩色多普勒值计算第二能量函数,并且确定 第二个总能量函数。
