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.
