  • Patent number: 10405829
    Abstract: An apparatus and method for generating high quality, high frame rate images in a handheld or hand-carried ultrasound imaging machine. The apparatus includes a time-multiplexed beamformer coefficient generator that supplies the necessary delay and weight coefficients to process multiple beams in parallel via a beamforming coefficient bus. This approach reduces the required hardware and power consumption to satisfy the physical space and power requirements of a handheld probe. To improve image quality, the ultrasound machine may optionally use synthetic aperture to improve penetration and resolution. The ultrasound machine may also use pulse inversion harmonics to improve image quality by improving signal-to-noise ratio.

  • Patent number: 10405836
    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.

  • Publication number: 20190090848
    Abstract: An ultrasound imaging system comprising a multi-use electronic display device and an ultrasound imaging device. The multi-use electronic display device is capable of communicating with one or more ultrasound imaging devices and selecting which to connect with based on at least one of previously store information, user input, and information gathered from the ultrasound imaging devices. The multi-use electronic display device may communicate with the ultrasound imaging devices while they are in a low power standby state. This approach reduces the complexity of the pairing process and provides a means for quickly and easily selecting between multiple ultrasound imaging devices.

  • Publication number: 20180333134
    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).

  • Publication number: 20180310922
    Abstract: This disclosure relates to methods and apparatus for performing at least three modes of ultrasound imaging using a single ultrasound transducer. In a first mode, transducer elements are activated so that ultrasound signals are transmitted from the contact surface at one or more directions normal to the contact surface. In a second mode, a first subset of the transducer elements are activated so that parallel ultrasound signals are transmitted from the contact surface. In a third mode, a second subset of the transducer elements are activated so that ultrasound signals are steered from the second subset of transducer elements.

  • Publication number: 20180220995
    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.

  • Patent number: 10039527
    Abstract: An ultrasound probe is equipped with a transducer element array and an internally located position marker trackable by a position sensing system or the like. The position marker is supported by a movement and rotation constraining fixture. The fixture is rigidly connected to the transducer element array of the probe. The fixture constrains the position and orientation of the position marker to match a spatial reference relationship with the transducer element array in the position marker's constrained degrees of freedom. The position marker may moved along and rotated in its unconstrained degrees of freedom to match the spatial reference relationship with the transducer element array.

  • Publication number: 20180140277
    Abstract: The present embodiments relate generally to ultrasound imaging systems. The ultrasound imaging systems may include an ultrasound imaging transducer operable to acquire ultrasound image data and a transducer adapter configured to detachably couple to the ultrasound imaging transducer. The transducer adapter may provide a different footprint from the ultrasound imaging transducer native footprint to enable the ultrasound imaging transducer adapter to acquire ultrasound image data in a substantially similar way to ultrasound transducers with different transducer geometry. The ultrasound imaging transducer may include a sensor for detecting an attachment state of the transducer adapter. The ultrasound imaging transducer may modify one or more imaging parameters when the transducer is attached to the ultrasound imaging transducer.

  • Patent number: 9895135
    Abstract: An ultrasound system has an ultrasound transducer equipped with a position marker and a needle equipped with a position marker. The position markers allow the position and orientation of the transducer and needle to be determined. A display depicts an ultrasound image acquired via the transducer and a graphical element representative of a projection of the longitudinal axis of the needle onto a plane of the ultrasound image. The quality of the position and orientation information from the position markers is monitored, and when quality is below a quality threshold the display indicates this fact.

  • Patent number: 9662088
    Abstract: Apparatus and methods for measuring and analyzing blood flow in vessels in the bodies of living subjects are provided. The true velocity vector, or a projection thereof onto a scan plane, for blood flowing at a location in a vessel is determined from multiple Doppler velocity components. The true velocity vector is displayed as a directional marker on an image comprising the vessel. The true velocity magnitude and angle, and scalar blood flow characteristics derived therefrom, are plotted as a functions of time and/or position across the depiction of the blood vessel in the image. Time intervals for which blood flow characteristic data is displayed and/or determined may be user configurable.

  • Publication number: 20170135672
    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.
