摘要： A diagnostic ultrasound image of a region of interest (ROI) of a body is formed by transmitting into the ROI at least a first and a second ultrasound pulse, in which the second pulse is phase-shifted relative to the first pulse by an amount other than 0 or a multiple of 180 degrees. Discretized receive signals from the pulses are interleaved to form a resultant operating signal that is detected and beamformed as the operating signal.

摘要： An ultrasonic blood flow imaging display method and an ultrasonic imaging system. The system comprises: a probe (1); a transmitting circuit (2), configured to excite the probe (1) to transmit an ultrasonic beam to a scanning target; a receiving circuit (4) and a beam forming module (5), configured to receive an echo of the ultrasonic beam to obtain an ultrasonic echo signal; a data processing module (9), configured to obtain, according to the ultrasonic echo signal, blood flow velocity vector information and Doppler blood flow velocity information about a target point in the scanning target and at least part of ultrasonic images of the scanning target, and superposing the ultrasonic images and the Doppler blood flow velocity information to form a Doppler color blood flow graph; and a display (8), configured to contrastively display the blood flow velocity vector information and the Doppler color blood flow graph. By means of a mode of contrastively displaying a common blood flow display image and a vector blood flow, a better viewing angle is provided for a user.
