  • Patent number: 11844644
    Abstract: The present embodiments relate generally to systems, methods, and apparatus for determining a heart rate of an imaged heart in an ultrasound image feed. A plurality of ultrasound images can first be acquired. For each ultrasound image of the plurality of ultrasound images, the image can be divided into a plurality of regions; where each region is positioned so that the region corresponds to a substantially similar region location present across the plurality of ultrasound images. For each region location on each of the plurality of ultrasound images, a statistical calculation on image data of the region location can be performed. For each region location, a frequency of change in the statistical calculation over the plurality of ultrasound images can then be determined. The region location having a dominant determined frequency of change in the statistical calculation (over the plurality of ultrasound images) can be identified as a region of interest (ROI).

  • Patent number: 11801035
    Abstract: An apparatus and method for providing remote expert feedback to an operator of an ultrasound imaging machine. The remote feedback consists of graphical icons that are dragged and dropped onto a video stream of the patient being scanned or the ultrasound image being captured and shared in real-time with the local operator to help improve their scanning technique.

  • Patent number: 11222402
    Abstract: A method of adaptive image enhancement, comprising, receiving a low resolution image, receiving at least one application constraint, detecting at least one scene within the low resolution image, detecting a plurality of regions of interest within the detected at least one scene, prioritizing the detected plurality of regions of interest, ranking the detected plurality of regions of interest based on the prioritization, determining an enhanceable subset of the plurality of regions of interest based on the ranking of the plurality of regions of interest and the at least one application constraint and enhancing the enhanceable subset of the plurality of regions of interest.

  • Publication number: 20210015464
    Abstract: The present embodiments relate generally to ultrasound imaging systems and methods that provide a user interface on the touchscreen display. The user interface includes an ultrasound image feed and a single control for modifying imaging depth of the ultrasound image feed. When input via the single control is received to modify the imaging depth, the system: adjusts frequency of ultrasound signals being used to acquire the ultrasound image feed; adjusts a beamformer parameter of the ultrasound signals being used to acquire the ultrasound image feed; receives first image data of the ultrasound image feed based on the adjusted frequency and the adjusted beamformer parameter; based on the first image data, adjusts Time Gain Compensation (TGC) of the ultrasound image feed; and receives second image data of the ultrasound image feed based on the adjusted frequency, beamformer parameter and TGC. Display of the second image data on the touchscreen display is then optimized without receipt of additional user input.

  • Publication number: 20200015790
    Abstract: An apparatus and method for generating high quality, high frame rate images in a handheld or hand-carried ultrasonic imaging machine. The apparatus includes an image enhancer to reduce speckle noise and improve the compressibility of the resulting image. This approach reduces the required hardware and power consumption to satisfy the physical space, power, and limited processing power of a handheld probe and enables high quality images to be transmitted efficiently over low-bandwidth connections.

  • Patent number: 10456108
    Abstract: An apparatus and method for automatically calculating and applying time gain compensation in a handheld or hand-carried ultrasonic imaging machine. The apparatus include an autogain unit to calculate the time gain compensation based on a processed ultrasound image. The image is divided into regions, and the image intensity is used to mask regions which satisfy a threshold. Masked regions are used to calculate a gain curve which is then spatially and temporally smoothed. Means are providing for masking entire columns of regions to remove areas where the probe is not in contact. This approach may allow less experienced users to achieve high quality images without the difficult and time-consuming task of manually adjusting the time gain compensation.
