  • Patent number: 11026663
    Abstract: Ultrasound imaging apparatus and method for veterinary applications. An ultrasound probe obtains ultrasound frame data which is compressed prior to wireless communication to a data processing unit. The data processing unit decompresses the ultrasound frame data and uses it to generate ultrasound images. The transmit bandwidth or transmit buffer size are monitored and the scan rate is reduced if required to maintain low latency. The apparatus generates images with lower latency and greater tolerance of variations in wireless data transfer bandwidth than where images are generated by an ultrasound probe and transmitted wirelessly to a remote display. A regularly updated image can be displayed even if image quality may be temporarily reduced.

  • Patent number: 10905398
    Abstract: Systems are provided for the arrangement of decoupled electric and acoustic modules for a transducer array of an ultrasound probe. In one embodiment, the decoupled modules are independently coupled to a flex interconnect, apart from one another, allowing for electric communication between all modules through the flex interconnect. As one example, an ultrasound transducer array for an ultrasound probe comprises an acoustic backing, a flex interconnect coupled to the backing at a first surface of the flex interconnect, a matrix acoustic array coupled to a second surface of the flex interconnect, the second surface opposite the first surface, and an electric module coupled to the second surface of the flex interconnect at a location spaced away from where the matrix acoustic array is coupled to the flex interconnect.

  • Patent number: 10905396
    Abstract: An ultrasound imaging system includes an interventional medical device having a first tracking element that generates tip location data based on an EM locator field. An ultrasound probe has an ultrasound transducer mechanism and a second tracking element. The ultrasound transducer mechanism has an active ultrasound transducer array that generates two-dimensional ultrasound slice data at any of a plurality of discrete imaging locations within a three-dimensional imaging volume. The second tracking element generates probe location data based on the EM locator field. A processor circuit is configured to execute program instructions to generate an ultrasound image for display, and is configured to generate a positioning signal based on the tip location data and the probe location data to dynamically position the active ultrasound transducer array so that the two-dimensional ultrasound slice data includes the distal tip of the interventional medical device.

  • Patent number: 10902596
    Abstract: Data from a tomographic scan (14) that provides three-dimensional information about a patient's brain comprises the steps of: filtering and re-sampling (21) the data to produce a three-dimensional image; performing registration (23) to align the three-dimensional image with a reference image (16), using 3-D rigid and/or non-rigid transformations; identifying (25) image features in the aligned image, to identify which voxels or regions of adjacent voxels correspond to image features that represent structures within the brain that are expected to be evident; classifying (26) each voxel within an identified image feature by a voxel score that corresponds to the difference between the attenuation of that voxel and the expected attenuation at that region of the brain; and deducing a cumulative score that combines the voxel scores from all the voxels of at least a region of the brain.

  • Patent number: 10893911
    Abstract: Systems, methods, and computer-readable media are provided. Some embodiments include obtaining image data of a subject and a medical device, the medical device including fiducial markers, wherein the image data includes three-dimensional image data. Information is generated representing a three-dimensional shape based on a planned insertion point for performing a medical procedure. A cropping process is applied to the image data to generate cropped image data based on the three-dimensional shape. In some embodiments, the cropped image data includes image data of at least two of the fiducial markers. Fiducial marker objects are detected within the cropped image data, and the fiducial marker objects are registered by matching a model of the fiducial markers with the fiducial marker objects.
