  • Patent number: 11103214
    Abstract: In one embodiment, an ultrasonic diagnostic apparatus includes a probe configured to be equipped with plural transducers arranged in a first direction and a second direction perpendicular to the first direction and be able to perform a two-dimensional scan in the first and second directions; a moving device configured to support the probe and mechanically move the probe in the second direction; a receiving circuit configured to generate first reception signals for respective moving positions of the probe in the second direction by performing receiving phase-compensation and summation processing on respective reflected signals received by the plurality of transducers at each of the moving positions; and processing circuitry configured to generate a second reception signal by performing moving aperture synthesis on the first reception signals generated for the respective moving positions of the probe based on positional information of the probe and generate image data from the second reception signal.

  • Publication number: 20180333138
    Abstract: According to one embodiment, an ultrasonic diagnostic apparatus includes a processor. The processor generates assistance information to assist an operation of a puncture needle based on pressure information acquired from a pressure sensor attached to the puncture needle. The processor displays on a display the assistance information and an ultrasonic image which includes at least an image of a tip of the puncture needle, the ultrasonic image being acquired by transmission and reception of ultrasonic waves by using an ultrasonic probe.

  • Publication number: 20180092629
    Abstract: According to one embodiment, an ultrasound diagnosis apparatus includes an image processing circuit and a processing circuit. The image processing circuit generates an ultrasound image. The processing circuit receives a medical image acquired by another medical image diagnosis apparatus, and aligns the ultrasound image and the medical image. The processing circuit has a function of recognizing identification information held by the medical image when the ultrasound image and the medical image are displayed side by side on a display. The processing circuit also has a function of retrieving diagnostic protocol information corresponding to the identification information and displaying it on the display, and a function of performing examinations and processes based on the diagnostic protocol information displayed.

  • Publication number: 20170007201
    Abstract: An ultrasonic diagnostic apparatus according to a present embodiment includes processing circuitry. The processing circuitry is configured to extract a cardiac valve from three-dimensional images of frames generated by controlling an ultrasonic probe to perform transmission and reception of ultrasonic waves. The processing circuitry is configured to calculate, as a prolapse gap, a gap between valve leaflets of the cardiac valve in a three-dimensional image of a specific frame among the frames. The processing circuitry is configured to display the prolapse gap on a display.
