Abstract: An ultrasound imaging system which uses multiline receive beamforming for synthetic transmit focusing are phase adjusted to account for speed of sound variation in the transmission medium. The phase discrepancy of the received multilines caused by speed of sound variation in the medium is estimated in the frequency domain for both the transmit angular spectrum and the receive angular spectrum. The phase variation is removed in the frequency domain, then an inverse Fourier transform is used to transform the frequency domain results to the spatial domain. In another implementation, the phase discrepancy of the received multilines is estimated and corrected entirely in the spatial domain.

Abstract: An ultrasound imaging system includes acoustic elements configured to transmit ultrasound energy and receive associated echoes. The system further includes a processor circuit in communication with the acoustic elements. The processor circuit may be configured to receive data corresponding to a set of subframes based on the echoes. The set of subframes includes a first and second subframe. The processor circuit may be configured to coherently combine data corresponding to a first portion of the first subframe and data corresponding to a first portion of the second subframe, which may both include phase information. The processor circuit may be configured to generate an image based on the coherent combination of the first portion of the first subframe and the first portion of the second subframe and to output the generated image to a display in communication with the processor circuit.

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: 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.

Abstract: An ultrasound imaging system (1) comprises an ultrasound transducer array (100) comprising a plurality of ultrasound transducer tiles (101a-d), each of said tiles having an independently adjustable orientation such as to conform an ultrasound transmitting surface to a region of a body (50) including a foreign object such as a pacemaker, a stent, or an interventional tool (200). Using a known spatial arrangement of a plurality of features (201-204) of the foreign object (200), the respective ultrasound images generated by the ultrasound transducer tiles are registered in order to generate a composite image, in which the position and orientation of the foreign object in the individual images is superimposed. The position and orientation of an interventional tool may be determined for each image using object recognition algorithms or using acoustic feedback information provided by at least three ultrasound sensors (201-204) arranged in a known spatial arrangement on the interventional tool.

Abstract: Systems and methods for reducing speckle while maintaining frame rate are disclosed. Multiple sub-images associated with different receive angles are acquired for a single transmit/receive event at an observation angle. The sub-images are compounded to generate a final image with reduced speckle. In some examples, multiple sub-images from multiple transmit/receive events are compounded to generate the final image. The observation angle and/or the receive angles may vary between transmit/receive events in some examples.

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: In some examples, received signals from certain multilines may be selectively filtered to remove aliased frequencies that may result in grating lobes in ultrasound images. In some examples, a transmit beam may be shaped to reduce spatial frequencies in received signals. In some examples, the width of the transmit beam may be adjusted based on a frequency of the transmit signal. In some examples, a focal depth of the transmit beam may be adjusted based on a frequency of the transmit signal.
