Ping-based and detection of movements with multiple openings Doppler ultrasound

摘要

All fields or Doppler ultrasound imaging method of "ping-based", without requiring a certain range gate, to permit detection of the Doppler signal indicating a reflector in motion at any point in the imaging field. In various embodiments, all such fields Doppler imaging method, the detecting step of transmitting the Doppler ping from the transmission aperture, the step of receiving an echo Doppler ping one or more separate receiving apertures, a Doppler signal step , and it may comprise the step of determining the velocity of motion to that reflector. In some embodiments, this system can also be used to determine the direction of motion by solving a set of simultaneous equations based on the echo data to be received by multiple receive aperture. .BACKGROUND
