摘要： A method for ultrasound flow imaging includes transmitting a set of transmission beams through a region of interest having a plurality of spatial locations. The method further includes generating demodulated data in response to the set of transmission beams. Further, the method includes obtaining a plurality of wave-number vectors and location response data corresponding to each spatial location. Moreover, the method includes determining a plurality of Doppler frequency values based on the location response data and determining a flow vector for each spatial location based on the plurality of Doppler frequency values and the plurality of wave-number vectors. The method also includes generating a flow vector image based on the flow vectors corresponding to the plurality of spatial locations within the region of interest, where the flow vector image is representative of a magnitude and direction of blood flow in the region of interest.

摘要： Techniques, systems, and devices are disclosed for synthetic aperture ultrasound imaging using spread-spectrum, wide instantaneous band, coherent, coded waveforms. In one aspect, a method includes synthesizing a composite waveform formed of a plurality of individual orthogonal coded waveforms that are mutually orthogonal to each other, correspond to different frequency bands and including a unique frequency with a corresponding phase; transmitting an acoustic wave based on the composite waveform toward a target from one or more transmitting positions; and receiving at one or more receiving positions acoustic energy returned from at least part of the target corresponding to the transmitted acoustic waveforms, in which the transmitting and receiving positions each include one or both of spatial positions of an array of transducer elements relative to the target and beam phase center positions of the array, and the transmitted acoustic waveforms and the returned acoustic waveforms produce an enlarged effective aperture.

摘要： A multiple aperture ultrasound imaging system may be configured to store raw, un-beamformed echo data. Stored echo data may be retrieved and re-beamformed using modified parameters in order to enhance the image or to reveal information that was not visible or not discernible in an original image. Raw echo data may also be transmitted over a network and beamformed by a remote device that is not physically proximate to the probe performing imaging. Such systems may allow physicians or other practitioners to manipulate echo data as though they were imaging the patient directly, even without the patient being present. Many unique diagnostic opportunities are made possible by such systems and methods.

摘要： Sold-state intravascular ultrasound (IVUS) imaging devices, systems, and methods are provided. Some embodiments of the present disclosure are particularly directed to flexible and efficient systems for focusing IVUS echo data received from transducers including polymer piezoelectric micro-machined ultrasound transducers (PMUTs). In one embodiment, an ultrasound processing system includes first and second aperture engines coupled to an engine controller, which provides aperture assignments to the first and second aperture engines. The aperture engines receive the assignment and a portion of A-line data, perform one or more focusing process on the received A-line data, and produce focused data in accordance with the aperture assignment. In some embodiments, once an aperture engine has produced focused data, the engine controller clears the aperture engine and assigns another aperture.
