  • Patent number: 10646196
    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: 10485508
    Abstract: An ultrasonic diagnostic device wherein: a Doppler processing unit acquires Doppler information in a living body on the basis of an ultrasonic reception signal; a velocity vector calculating unit acquires the velocity vector distribution of a blood stream in the living body on the basis of the Doppler information in the living body; and, to form a flow line showing the flow of the blood stream on the basis of the velocity vector distribution, a flow line forming unit searches for a proper start point by inversely tracing the flow of the blood stream from an initial start point along the reverse direction of the velocity vector and then forms a flow line extended from the proper start point.

  • Patent number: 10398407
    Abstract: An ultrasonic diagnostic imaging system is described which quantifies regurgitant flow through a mitral valve. Echo signals received by an ultrasound probe (10) are used to produce an image of a regurgitant flow region, and are processed by a wall filter having a response characteristic which peaks at an intermediate sampling rate between zero and the Nyquist limits. This response characteristic is thus highly sensitive to lower flow rates which may be anticipated in a flow velocity field proximal a regurgitant orifice. Echo signals passed by the wall filter are Doppler processed and used to quantify the flow through the regurgitant orifice.

  • Patent number: 10383596
    Abstract: An intravascular ultrasound probe is disclosed, incorporating features for utilizing an advanced transducer technology on a rotating transducer shaft. In particular, the probe accommodates the transmission of the multitude of signals across the boundary between the rotary and stationary components of the probe required to support an advanced transducer technology. These advanced transducer technologies offer the potential for increased bandwidth, improved beam profiles, better signal to noise ratio, reduced manufacturing costs, advanced tissue characterization algorithms, and other desirable features. Furthermore, the inclusion of electronic components on the spinning side of the probe can be highly advantageous in terms of preserving maximum signal to noise ratio and signal fidelity, along with other performance benefits.

  • Patent number: 10342515
    Abstract: An ultrasound system performs duplex colorflow and spectral Doppler imaging, with the spectral Doppler interrogation performed at a sample volume location shown on the colorflow image. The colorflow image is displayed in a color box overlaid on a co-registered B mode image. A color box position and steering angle processor analyzes the spatial Doppler data and automatically sets the color box angle and location over a blood vessel for optimal Doppler sensitivity and accuracy. The processor may also automatically set the flow angle correction cursor in alignment with the direction of flow. In a preferred embodiment these optimization adjustments are made automatically and continuously as a user pauses at points for Doppler measurements along a length of the blood vessel.

  • Patent number: 10231691
    Abstract: An audible ultrasound physical examination device alters ultrasound to an audible range such that audible feedback can be used to enhance physical examination to detect anatomical abnormality and determine if more refined testing is warranted. The device includes a chestpiece and an ultrasound probe coupled to the chestpiece. The ultrasound probe projects an initial sound wave towards a first face of the chestpiece and into a human body such that a reflected wave is produced when the initial sound wave is reflected by matter with the human body. A sonic converter, coupled to the chestpiece, introduces an interference wave creating destructive interference to produce a resulting wave within an audible range. An earpiece is coupled to the chestpiece such that the resulting wave in the audible range is audible through the earpiece.
