    Abstract: Improved ultrasound imaging devices and methods of using the devices are provided. An intraluminal imaging device is configured process imaging data obtained using a single imaging sequence in different processing paths to generate B-mode and flow images. For example, an ultrasound imaging system includes an ultrasound imaging device comprising an array of acoustic elements and a processor in communication with the array. The processor activates the array of acoustic elements to acquire ultrasound data using a sequence of transmit-receive pairs, generates a B-mode image using the acquired ultrasound data, forms a plurality of sub-apertures comprising a portion of the transmit-receive pairs, groups the sub-apertures into temporally-spaced ensembles, determines a flow estimate based on a comparison of at least one of sub-apertures within an ensemble, ensembles within an aperture, or different apertures, and outputs a graphical representation of the B-mode image and the flow estimate to a display.

    Abstract: An ultrasound system produces high quality images at a high framerate of display. A plane or volume to be imaged is scanned by different diverging transmit beams to acquire a series of different sub-frames, the number of sub-frame acquisitions comprising a total number of transmit beams which would produce a high quality image. The echoes received in response to the transmit beams of a sub-frame are coherently combined with the echoes received in other sub-frames. Each time the echoes of a new sub-frame have been coherently combined with the echoes of all other different sub-frames, a full image is produced. After a complete series of sub-frames has been received and the echoes combined, another series of sub-frame acquisition is commenced and a new series of sub-frames acquired. As each new sub-frame is acquired, it is coherently combined with all the other different and most recently acquired sub-frames. This technique produces a new image at the sub-frame scanning rate, rather than awaiting a completely new series of sub-frames before forming a new image.

    Abstract: Systems, methods, and devices that perform flow scan sequences are provided. In one embodiment, an ultrasound imaging system includes an intraluminal catheter or guidewire, an annular array of acoustic elements positioned around a circumference of the catheter or guidewire, and a processor in communication with the annular array. The processor is configured to activate a first subaperture of the annular array at a first time, thereafter, activate a second interleaving subaperture, and activate the first subaperture again at a different, second time such that the scan sequence moves around the circumference of the catheter or guidewire. Temporal differences between the received ultrasound signals obtained by the first subaperture at the first and second times are determined to detect motion around the annular array. By interleaving subaperture firings, the total number of firings to form an image frame can be reduced.

    Abstract: Improved ultrasound imaging devices and methods of operating the devices that minimize grating lobe artifacts in an ultrasound image are provided. For example, an ultrasound imaging system analyzes the ultrasound data at different frequency bands and generates a grating-lobe-minimized image based on minimum signals identified for each pixel among the plurality of frequency ranges. In one embodiment, an ultrasound imaging system includes an ultrasound transducer array configured to obtain ultrasound data, and a processor in communication with the ultrasound transducer array. The processor is configured to receive the ultrasound data, generate an ultrasound image based on a first frequency range of the ultrasound data, generate a grating-lobe-minimized ultrasound image based on a plurality of second frequency ranges of the ultrasound data, combine the ultrasound image and the grating-lobe-minimized ultrasound image to generate a combined ultrasound image, and output the combined ultrasound image to a display.

    Abstract: Ultrasound imaging systems and methods for generated clutter-reduced images are provided. For example, an ultrasound imaging system can include an array of acoustic elements in communication with a processor. The processor is configured to activate the array to perform a scan sequence to obtain a plurality of signals, identify off-axis signals from the plurality of signals by comparing the right subaperture and the left subaperture, and create a clutter-reduced image based on the comparison. Because off-axis signals are more likely to create image clutter, reducing the influence of off-axis signals on the image can therefore improve the quality of the image. Accordingly, embodiments of the present disclosure provide systems, methods, and devices for generating ultrasound images that have reduced or minimized clutter, even for images obtained using arrays that do not satisfy the Nyquist criterion.
