Appl. No.:

17/992423

International Classification:

A61B 8/06
A61B 8/00
A61B 8/08

Abstract:

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.

International Classification:

A61B 8/14
A61B 8/00

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.

International Classification:

A63F 13/798
A63F 13/211
A63F 13/77
A63F 13/90

Abstract:

Embodiments of the systems and methods disclosed herein provide a gaming console and gaming controllers, including hardware and software features included on the hardware. For example, a game balancing system is described that can monitor and track performance data from one or more players of the gaming console. With the performance data, artificial intelligence and machine learning can be used to create one or more models that are applied to determine adjustments to games being played on the gaming console. The adjustments to the games can be implemented specifically to each game, player, or set of players to achieve more balanced gameplay as measured by game outcomes and other factors.

G06T 7/00

Abstract:

Aspects of the invention include ultrasound systems that suppress grating lobe artifacts arising due to high frequency operation of an array transducer probe which is operated at a frequency higher than its pitch limitation.
