  • Patent number: 10667790
    Abstract: Exemplary embodiments provide systems and methods for portable medical ultrasound imaging. Certain embodiments provide a multi-chip module for an ultrasound engine of a portable medical ultrasound imaging system, in which a transmit/receive chip, an amplifier chip and a beamformer chip are assembled in a vertically stacked configuration. Exemplary embodiments also provide an ultrasound engine circuit board including one or more multi-chip modules, and a portable medical ultrasound imaging system including an ultrasound engine circuit board with one or more multi-chip modules. Exemplary embodiments also provide methods for fabricating and assembling multi-chip modules as taught herein. A single circuit board of an ultrasound engine with one or more multi-chip modules may include 16 to 128 channels in some embodiments. Due to the vertical stacking arrangement of the multi-chip modules, a 128-channel ultrasound engine circuit board can be assembled within exemplary planar dimensions of about 10 cm×about 10 cm.

  • Patent number: 10426435
    Abstract: The present invention related to an ultrasound imaging system win which the scan head includes a beamformer circuit that performs far field subarray beamforming or includes a sparse array selecting circuit that actuates selected elements. When using a hierarchical two-stage or three-stage beamforming system, three dimensional ultrasound images can be generated in real-time. The invention further relates to flexible printed circuit boards in the probe head. The invention furthermore related to the use of coded or spread spectrum signaling in ultrasound imagining systems. Matched filters based on pulse compression using Golay code pairs improve the signal-to-noise ratio thus enabling third harmonic imaging with suppressed sidelobes. The system is suitable for 3D full volume cardiac imaging.

  • Patent number: 9402601
    Abstract: A hand-held ultrasound system includes integrated electronics within an ergonomic housing. The electronics includes control circuitry, beamforming and circuitry transducer drive circuitry. The electronics communicate with a host computer using an industry standard high speed serial bus. The ultrasonic imaging system is operable on a standard, commercially available, user computing device without specific hardware modifications, and is adapted to interface with an external application without modification to the ultrasonic imaging system to allow a user to gather ultrasonic data on a standard user computing device such as a PC, and employ the data so gathered via an independent external application without requiring a custom system, expensive hardware modifications, or system rebuilds.

  • Publication number: 20150065879
    Abstract: A system and method for real-time quantitative analysis of heart wall motion is provided. A Doppler imaging system is used to monitor the movement of a heart, or other organ. A B-mode reference image of the target organ is made and then a region-of-interest is defined through the use of a gate. Then pulsed wave spectral tissue Doppler data of the region-of-interest is formed and used to determine the velocity of a region of the target organ. The system may be used for determining appropriate biventricular pacemaker settings for patients suffering from heart disease.
