摘要：
A method of full-field or “ping-based” Doppler ultrasound imaging allows for detection of Doppler signals indicating moving reflectors at any point in an imaging field without the need to pre-define range gates. In various embodiments, such whole-field Doppler imaging methods may include transmitting a Doppler ping from a transmit aperture, receiving echoes of the Doppler ping with one or more separate receive apertures, detecting Doppler signals and determining the speed of moving reflectors. In some embodiments, the system also provides the ability to determine the direction of motion by solving a set of simultaneous equations based on echo data received by multiple receive apertures.一種全域或「以回音為基」都卜勒超音波成像之方法允許於成像域中任何點偵測標示移動反射體之都卜勒信號,而不需預定義距離閘。在各式實施例中,該等全域都卜勒成像方法可包括從傳輸孔徑傳輸都卜勒聲納脈波、以一或多個不同接收孔徑接收該都卜勒聲納脈波之回音、偵測都卜勒信號及決定移動反射體之速度。在若干實施例中,該系統亦提供能力以藉由依據由多接收孔徑接收之回音資料解決一組聯立方程式而決定移動方向。
