  • Patent number: 10402969
    Abstract: Systems and methods are provided for a visualization of a multi-modal medical image for diagnostic medical imaging. The systems and methods receive first and second image data sets of an anatomical structure of interest, register the first and second image data sets to a geometrical model of the anatomical structure of interest to form a registered image. The geometrical model includes a location of an anatomical marker. The systems and methods further display the registered image.

  • Patent number: 10353069
    Abstract: An ultrasonic diagnostic imaging system is described by which a first sequence of ultrasound images of an organ such as the heart is acquired at a first image acquisition rate. The first sequence preferably images a larger volume or area in which a region of interest is located. Then a second sequence of three-dimensional ultrasound images of a sub-volume covering a part of anatomy of interest in the first sequence is acquired at a second image acquisition rate which is greater than the first acquisition rate. A third sequence of three-dimensional ultrasound images of a reference sub-volume is acquired at the second image rate. The second and third sequences of three-dimensional images are compared, enabling a clinician to focus on synchronism defects in the anatomy of interest with more precision and with a faster acquisition time.

  • Publication number: 20190140598
    Abstract: A multiple-stage amplifier includes a driver stage die and a final stage die. The driver stage die includes a first type of semiconductor substrate (e.g., a silicon substrate), a first transistor, and an integrated portion of an interstage impedance matching circuit. A control terminal of the first transistor is electrically coupled to an RF signal input terminal of the driver stage die, and the integrated portion of the interstage impedance matching circuit is electrically coupled between a current-carrying terminal of the first transistor and an RF signal output terminal of the driver stage die. The second die includes a III-V semiconductor substrate (e.g., a GaN substrate) and a second transistor. A connection, which is a non-integrated portion of the interstage impedance matching circuit, is electrically coupled between the RF signal output terminal of the driver stage die and an RF signal input terminal of the final stage die.

  • Publication number: 20190008480
    Abstract: The systems and methods described herein generally relate to identifying ultrasound images from multiple ultrasound exams. The systems and methods identify a first ultrasound image feature of a current ultrasound image of an anatomical structure during a current ultrasound exam based on ultrasound data received from an ultrasound probe, and accessing a plurality of prior ultrasound images that were acquired during a prior ultrasound exam. The systems and methods compare the first ultrasound image feature in the current ultrasound image with related ultrasound image features in the plurality of prior ultrasound images to identify candidate ultrasound images. The systems and methods identify a resultant ultrasound image from the candidate ultrasound images based on the related ultrasound image features, and display the current and resultant ultrasound images on a display.

  • Publication number: 20180322627
    Abstract: Systems and methods described herein generally relate to acquiring medical images for a protocol of an ultrasound exam. The systems and methods select a protocol of an ultrasound exam. The protocol includes a plurality of protocol defined fields of view (FOVs) of an anatomical structure of interest. The system and methods generate a medical image of the anatomical structure of interest based on ultrasound data acquired from an ultrasound probe, and identify a candidate FOV associated with the anatomical structure of interest based on anatomical markers of the medical image. The systems and methods also indicate on a graphical user interface (GUI) that the candidate FOV is acquired such that a select characteristic of a first user interface component of the GUI representing the candidate FOV is adjusted while the remaining user interface components representing the plurality of protocol defined FOVs do not include the select characteristic.

  • Publication number: 20180235573
    Abstract: Methods and systems are provided for multi-modality imaging. In one embodiment, a method comprises: during an ultrasound scan of a patient, co-aligning an ultrasound image received during the ultrasound scan with a three-dimensional (3D) image of the patient acquired with an imaging modality prior to the ultrasound scan; calculating an angle for an x-ray source based on position information in the 3D image to align the x-ray source with the ultrasound image; and adjusting a position of the x-ray source based on the calculated angle. In this way, the same internal views of a patient may be obtained with multiple modalities during an intervention with minimal user input.
