  • Patent number: 11147539
    Abstract: The systems and methods generally relate to blood speckle imaging. The systems and methods transmit a plurality of transmit (Tx) beams from an ultrasound probe to a region of interest (ROI). The plurality of Tx beams are transmitted successively with respect to each other. At least two of the plurality of Tx beams overlap at a common position. The systems and methods estimate velocity fields from the speckle tracking, and weight the velocity fields based on weighting signals to form weighted velocity fields. The weighting signal being centered at transmit beam axes of the plurality of Tx beams. The systems and methods interpolate the weighted velocity fields that overlap at the common position to adjust a portion of the weighted velocity fields, and generate an image on a display of a combined velocity field by combining the weighted velocity fields.

  • Patent number: 10803612
    Abstract: A system and method for recognizing structures in 3D ultrasound data based on volume renderings is provided. The method includes receiving 3D volume labels identifying a location of a structure in 3D training volumes. The method includes rendering each 3D training volume into multiple training volume renderings at multiple viewing angles. Each training volume rendering is associated with a volume rendering label corresponding with the 3D volume label. The method includes training a machine learning algorithm using the training volume renderings and associated volume rendering labels. The method includes acquiring and/or receiving a 3D volume and rendering it at a viewing angle. The method includes applying the machine learning algorithm to the volume rendering to detect and output the location of the structure. The method includes storing the location of the structure in the volume rendering in association with the 3D volume at a storage medium.

  • Publication number: 20180235573
    Abstract: Methods and systems are provided for multi-modality imaging. In one embodiment, a method comprises: during an ultrasound scan of a patient, co-aligning an ultrasound image received during the ultrasound scan with a three-dimensional (3D) image of the patient acquired with an imaging modality prior to the ultrasound scan; calculating an angle for an x-ray source based on position information in the 3D image to align the x-ray source with the ultrasound image; and adjusting a position of the x-ray source based on the calculated angle. In this way, the same internal views of a patient may be obtained with multiple modalities during an intervention with minimal user input.

  • Publication number: 20180235701
    Abstract: Methods and systems are provided for multi-modality imaging. In one embodiment, a method comprises: receiving planning annotations of a pre-operative three-dimensional (3D) image of a subject; during an ultrasound scan of the subject, registering an ultrasound image with the 3D image; overlaying the planning annotations on the ultrasound image; and displaying the ultrasound image with the overlaid planning annotations. In this way, pre-operative planning by a physician can be readily used during intervention.

  • Patent number: 9924922
    Abstract: Disclosed is a process for displaying ultrasound data representative of a rotationally symmetrical contractible chamber or vessel within a patient which involves obtaining ultrasound data from the ultrasound imaging of the vessel or chamber through at least a phase of one cardiac cycle and virtually sectioning the vessel or chamber into multiple circumferential segments, each extending its own longitudinal distance from a common reference point. The data is used to obtain rotational parameters representative of an entire circumferential segment of the chamber or vessel. The process is repeated until a rotational parameter for each entire circumferential segment along a desired distance of the longitudinal axis of the chamber or vessel has been obtained. The rotational parameters are displayed in a two dimensional format having annular rings with each annular ring being representative of a given circumferential segment.

  • Patent number: 8326007
    Abstract: A method for combined 4D presentation of quantitative measurements and morphology of an object uses an apparatus that includes a computer or processor, memory, and a display. The method includes identifying a region of interest in volumetric image data. Then, the following steps are iterated to produce a 4D volume rendering. The iterated steps include tracking a wall of the object in the region of interest of the image data to produce a displacement field, applying the displacement field to display data to create enhanced rendering data, volume rendering the enhanced rendering data to produce an enhanced volume rendering, and displaying the enhanced volume rendering.
