  • Publication number: 20230200784
    Abstract: An ultrasonic diagnostic device includes an ultrasonic probe and processing circuitry. The probe conducts ultrasonic scanning on a three-dimensional area of a subject and receives a reflected wave from the subject. The circuitry acquires the correspondence relation between a position in ultrasonic image data on the three-dimensional area based on the reflected wave and a position in volume data on the subject captured by a different medical-image diagnostic device. The circuitry receives, from an operator, an operation to set a position marker, which indicates the position at which blood-flow information is extracted, on a scan area of the ultrasonic image data. The circuitry causes the image generated during a rendering process on the ultrasonic image data to be displayed and causes the position marker to be displayed at a corresponding position on a display image based on at least the volume data in accordance with the correspondence relation.

  • Patent number: 11290740
    Abstract: A detection unit successively selects each of a plurality of blocks of a target image as a target block and detects a motion vector of the target block using a reference image. During motion vector detection, a control unit performs control to partially store the reference image into a storage unit so as to achieve a state where a search range for the target block is stored. The detection unit selects each of the plurality of blocks as the target block in an order of raster scan for each of N regions obtained by dividing the target image in a horizontal direction. When a temporal distance between the target image and the reference image is a second distance that is longer than a first distance, a value of N is large compared to a case where the temporal distance is the first distance.
