A method for ultrasonic imaging comprises: emitting Doppler pulses to a target to be detected; performing a Doppler scan with Doppler pulses; receiving echo signals from the target, wherein the echo signals include Doppler pulse echo signals; processing the echo signals, wherein processing comprises an imaging step, the imaging step comprising parallel processing steps including a 2D image processing step, a flow image processing step, and a spectrum image processing step, wherein the 2D image processing step is configured for processing the echo signals to obtain 2D image signals, the flow image processing step is configured for processing the echo signals to obtain flow image signals, and the spectrum image processing step is configured for processing the echo signals to obtain spectrum image signals; and displaying the processed echo signals.

Methods and systems for ultrasonic imaging

Elements in an ultrasound array are activated according to a transmit beamformer to create a series of transmit beams. For each transmit beam, the first stage of a receive beamformer determines a plurality of primary receive beams. A second beamformer stage then computes secondary receive beams as a function of the primary receive beams that correspond to return signals from different transmit beams to a common receive beam origin. For example, each secondary receive beam may be calculated as a function of the weighted, time-delayed sum of the primary receive beams. At least one of the secondary receive beams is then output from the beamformer to be used in creating a displayed image.

Multi-stage digital ultrasound beamformer

A method displays ultrasound color flow image data in a plurality of output frames by continuously acquiring color flow image data. Each output frame includes a plurality of scan lines that collectively represent a field of view for an ultrasound image. The method includes sequentially transmitting a plurality of ultrasound beams. For each of the transmitted beams, multiple receive beams are formed along respective parallel scan lines. As the sequence progresses, sets of co-linear receive beams are formed along each of the respective scan lines at a predetermined rate both within a particular frame and between successive frames. The method also includes processing the sets of co-linear receive beams along each of the respective scan lines to generate color flow image data corresponding to the respective scan lines, and displaying a color flow image representing the generated color flow image data.
