The present disclosure describes systems and methods for determining if a feature of interest is present in a volume or plane scanned by an imaging system. In examples, one or more imaging planes are analyzed for anatomical landmarks to determine whether a feature of interest is present. If the feature of interest is present, scan parameters may be determined to scan an adjusted volume that includes the feature of interest. In some applications, the adjusted volume may allow the imaging system to increase a volume rate.

Systems and methods for controlling volume rate

A system for visualization and quantification of ultrasound imaging data according to embodiments of the present disclosure may include a display unit, and a processor communicatively coupled to the display unit and to an ultrasound imaging apparatus for generating an image from ultrasound data representative of a bodily structure and fluid flowing within the bodily structure. The processor may be configured to estimate axial and lateral velocity components of the fluid flowing within the bodily structure, determine a plurality of flow directions within the image based on the axial and lateral velocity components, differentially encode the flow directions based on flow direction angle to generate a flow direction map, and cause the display unit to concurrently display the image including the bodily structure overlaid with the flow direction map.

Systems and methods for automatic detection and visualization of turbulent blood flow using vector flow data

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.

A system for visualization and quantification of ultrasound imaging data may include a display unit, and a processor communicatively coupled to the display unit and to an ultrasound imaging apparatus for generating an image from ultrasound data representative of a bodily structure and fluid flowing within the bodily structure. The processor may be configured to generate vector field data corresponding to the fluid flow, wherein the vector field data comprises axial and lateral velocity components of the fluid, extract spatiotemporal information from the vector field data at one or more user-selected points within the image, and cause the display unit to concurrently display the spatiotemporal information at the one or more user-selected points with the image including a graphical representation of the vector field data overlaid on the image, wherein the spatiotemporal information includes at least one of a magnitude and an angle of the fluid flow.

A method of power Doppler imaging may include receiving a plurality of temporally sequential frames of wall-filtered power Doppler signals, wherein the plurality of temporally sequential frames includes at least one previously adjusted output frame. The method may further include adjusting at least one of the plurality of temporally sequential frames to produce an adjusted output frame and generating a power Doppler image based, at least in part, on the adjusted output frame. The adjusting may involve filtering the plurality of temporally sequential frames to suppress the high spatial frequency and high temporal frequency content to produce the adjusted output frame.

Power doppler imaging system and method with improved clutter suppression

A system according to the present disclosure may include a display unit, a processor communicatively coupled to the display unit and to an ultrasound imaging apparatus for generating an image from ultrasound data representative of a bodily structure and fluid flowing within the bodily structure. The processor may be configured to generate vector field data including axial and lateral (or transverse) velocity components of the fluid flowing within the bodily structure, calculate velocity profiles for a plurality of locations along a wall of the bodily structure based on the axial and lateral velocity components, generate wall shear stress (WSS) visualization data based, at least in part, on the velocity profiles, and cause the display unit to concurrently display the image including the bodily structure overlaid with the WSS visualization data.

System and method for concurrent visualization and quantification of wall shear stress in blood vessels

An ultrasound system with a deep learning neural network feature is used to eliminate haze artifacts in B mode images of the carotid artery by analysis of orthogonal information. In a described implementation the orthogonal information comprises the structural information of a B mode image and motion information of the same field of view as that of the B mode image. In another embodiment the neural network reduces haze artifacts by reducing TGC gain at the depth of artifacts.

Ultrasound system with deep learning network for image artifact identification and removal

An ultrasound system with a matrix array () probe () operable in the biplane mode is used to assess stenosis of a blood vessel by simultaneously displaying two color Doppler biplane images () of the vessel, one a longitudinal cross-sectional view () and the other a transverse cross-sectional view (). The two image planes intersect along a Doppler beam line () used for PW Doppler. A sample volume graphic (SV) is positioned over the blood vessel at the peak velocity location in one image, then positioned over the blood vessel at the peak velocity location in the other image. As the sample volume location is moved in one image, the plane and/or sample volume location of the other image is adjusted correspondingly. Spectral Doppler data () is then acquired and displayed from the sample volume location.

Automated biplane-PW workflow for ultrasonic stenosis assessment

An ultrasound system and method provide a workflow to acquire 3D images of the fetal heart gated by a synthetic heart gating signal. An ROI is defined in an ultrasound image which delineates the fetal heart. The ultrasound system is controlled to automatically estimate the fetal heart rate from echo signals received from the ROI. When the system has acquired a stable synthetic heart rate signal, an indication thereof is given to the user and the user then commands the system to acquire 3D fetal heart images for a number of fetal heart cycles which are gated using the synthetic heart rate signal.

Automated heart rate detection for 3D ultrasonic fetal imaging

An ultrasonic diagnostic system is provided which detects the presence of coated microbubble contrast agents in the body of a patient by transmitting ultrasonic energy which causes the destruction of the coated microbubbles and detects the microbubble destruction through phase insensitive detection and differentiation of echoes received from two consecutive ultrasonic transmissions. The destruction of a microbubble can also be used as a point source of acoustic energy for aberration correction, whereby the timing of the beamformer is adjusted from an analysis of beamformer signals resulting from a detected microbubble destruction event.

Ultrasonic detection of contrast agents

Apparatus for guiding the movement of a hand held router relative to a workpiece comprises a support forming an upwardly facing base adapted to underlie and support a workpiece to be routed. A plurality of parallel guide posts extend upwardly from the support and carry a rigid frame having an open central portion. The frame is mounted on the guide posts for guided sliding movement toward and away from the base to overlie a workpiece supported on the base. Springs bias the frame away from the base and clamps act to overcome the bias and clamp the frame into engagement with the uppermost surface of a workpiece supported on the base. A router guide template is removably connected in the open central portion of the rigid frame at a location to substantially engage the uppermost surface of a workpiece support on the base when the frame is clamped into engagement therewith.
