  • Patent number: 11719797
    Abstract: The invention provides a method for controlling the generation of a compound ultrasonic image. The method includes obtaining a first ultrasound image and applying adaptive beamforming to the first ultrasound image, thereby generating a second ultrasound image. A weighting is determined based on the first and second ultrasound images, wherein the weighting comprises at least one weighting component. The compound ultrasound image is then generated based on the first and second ultrasound images and the weighting component.

  • Patent number: 11419581
    Abstract: An ultrasonic imaging system acquires frames of echo data at a high acquisition frame rate using a single mode of acquisition. The echo data is used by three image processors to produce an anatomical image, a mechanical function image, and a hemodynamic image from the same echo data. A display displays an anatomical image, a mechanical function image, and a hemodynamic image simultaneously.

  • Patent number: 11284910
    Abstract: A therapeutic ultrasound system transmits a staggered or interleaved pattern of therapy beams for use in sonothrombolysis and other Vascular Acoustic Resonators (VAR) mediated therapy. The inventive technique minimizes VAR, e.g. microbubble, destruction due to adjacent beams, ensures uniform sonication of the targeted region by filling in the spaces between the beams in subsequent passes, and further provides a means for bubble replenishment to maximize the clot lysis from ultrasound. The technique is also applicable to diagnostic ultrasound, VAR mediated drug delivery and blood brain barrier opening.

  • Publication number: 20220079551
    Abstract: The invention provides a method for assessing cardiac valve regurgitation. The method includes obtaining 4D ultrasound data of a region of interest, wherein the region of interest comprises a cardiac valve. The 4D ultrasound data comprises a time sequence of 3D ultrasound images comprising B-mode ultrasound data and color Doppler ultrasound data. Image stabilization is performed on the images of the time sequence of 3D ultrasound images and a dynamic jet is then segmented from the time sequence of stabilized 3D ultrasound images. A dynamic surface model is fit to the valve in the time sequence of stabilized 3D ultrasound images based on the segmented jet. The method further includes identifying a dynamic regurgitant orifice based on the applied surface model and the time sequence of stabilized 3D ultrasound images and fitting a flow convergence model to the time sequence of stabilized 3D ultrasound images based on the identified dynamic regurgitant orifice.

  • Publication number: 20210353260
    Abstract: The present disclosure describes ultrasound imaging systems and methods for ultrasonically inspecting biological tissue. An ultrasound imaging system according to the present disclosure may be configured to automatically apply tissue-specific imaging parameter settings (312, 314) based upon the automatic identification of the type of tissue being scanned. Tissue type identification (315) may be performed automatically for the images in the live image stream (304) and thus adjustments to the imaging settings may be applied automatically by using a neural network (320) and thus dynamically during the exam obviating the need for the sonographer to manually switch presets or adjust the imaging settings when moving to different portion of the anatomy.

  • Patent number: 10952703
    Abstract: An ultrasound system is described which produces blended fundamental and harmonic frequency images. Successively transmitted, differently modulated pulses are transmitted by an ultrasound probe and both fundamental and harmonic frequencies are received in response. The echo signals received from the two pulses are processed by pulse inversion, producing cleanly separated bands of fundamental and harmonic signals in which undesired components have been cancelled. Since the two bands have been separated by signal cancellation rather than filtering, the two bands are allowed to overlap, providing broadband signals in each band. The bands are filtered by bandpass filtering to define the fundamental and harmonic signals to be imaged. The signals are detected, and the detected signals are combined after weighting to produce a blended fundamental/harmonic image.

  • Patent number: 10736611
    Abstract: An ultrasonic diagnostic imaging system is gated to acquire images at different phases of a physiological cycle such as the heartbeat. At each successive heart cycle a trigger actuates the acquisition of a continuous sequence of images, starting at a particular phase of the heart cycle and ending when the next heart cycle begins. Multiple triggers are used, each starting at a different phase of the heart cycle and each acquiring images at uniform temporal spacing. After the first trigger is used a sequence of images has been captured which are temporally evenly spaced over the heart cycle, and as successive triggers are used uniform temporal spacing is maintained as the heart cycle is filled in with additional images for replay of an image loop of phase re-ordered images at a high frame rate of display.

  • Publication number: 20190029651
    Abstract: An ultrasonic diagnostic imaging system and method filter the data of successive ultrasonic images of moving tissue. At least two successive images are clutter filtered to remove clutter in the image data from stationary objects. The successive images and the filtered successive images are both used to produce displacement images of frame to frame tissue motion, and a quality metric is produced of the quality of the estimated displacement. The displacement image with the best quality metric is selected for further processing such as the production of strain images. The selected displacement image may further be spatially filtered to reduce boundary artifacts.
