摘要： Ultrasound imaging system and method that provides user- or situationally-adjustable interleaved imaging modes are described. An ultrasound system according to the present disclosure includes a user interface that enables the user to interact with the system to specify or otherwise control the priority of one mode of the other modes in a multi-mode imaging operation.

摘要： An ultrasonic diagnostic imaging system scans a plurality of planar slices in a volumetric region which are parallel to each other. Following detection of the image data of the slices the slice data is combined by projecting the data in the elevation dimension to produce a “thick slice” image. Combining may be by means of an averaging or maximum intensity detection or weighting process or by raycasting in the elevation dimension in a volumetric rendering process. Thick slice images are displayed at a high frame rate of display by combining a newly acquired slice with slices previously acquired from different elevational planes which were used in a previous combination. A new thick slice image may be produced each time at least one of the slice images is updated by a newly acquired slice. Frame rate is further improved by multiline acquisition of the slices.

摘要： The present disclosure describes ultrasound systems configured to enhance flow imaging and analysis by adaptively adjusting one or more imaging parameters in response to acquired flow measurements. Example systems can include an ultrasound transducer and one or more processors. Using the system components, mean flow velocity magnitude and acceleration can be determined within a target region during an acquisition phase, which may include a cardiac cycle. One or more adjusted flow imaging parameters, such as adjusted ensemble length, temporal smoothing filter length and/or step size, can be determined based on the acquired flow measurements to increase the signal quality of newly acquired ultrasound echo signals. The adjusted flow imaging parameters can then be applied by the ultrasound transducer during a second acquisition phase.

摘要： Encoded transmit signals are provided to an ultrasound array such diverging ultrasound waves are sequentially transmitted. Each diverging ultrasound wave is generated by a respective set of encoded transmit signals, where each set of encoded transmit signals is encoded by a respective row of an N×N invertible orthogonal matrix. Only a selected subset of M rows, with N

摘要： A method and apparatus for generating a shear wave. The method comprises: transducers transmit ultrasound waves to a region of interest once; the ultrasound waves focus on at least two focal points in an acoustic field; and with shear wave sources corresponding to the at least two focal points that propagates in a direction perpendicular to a transmission direction of the ultrasound waves. A method and apparatus for detecting an ultrasound elasticity of a shear wave discloses, in a same ultrasound transmission, multiple focal points are gathered in an acoustic field by the ultrasound waves, under the joint effect of the multiple focal points, and a shear wave zone propagated in a direction perpendicular to a direction in which the ultrasound waves is transmitted is formed, so as to expand a propagation range of the shear wave in a tissue, so that detecting ultrasound waves can perform elasticity detection on the tissue in a large range.
