  • Patent number: 11103219
    Abstract: An ultrasound diagnostic apparatus includes the following. A deflection controller generates delay time information to make phases of reception signals input to channels uniform according to a deflection angle. A channel selector selects a channel in which the reception signal is turned on or off so that the phases of the reception signals input to channels are different and which generates channel selection information. A reception delay interrupter provides the delay amount to the reception signal and which turns on or off the reception signal. An adder adds the plurality of reception signals which are provided with the delay amount and turned on.

  • Publication number: 20210228183
    Abstract: A diagnostic ultrasound apparatus includes a body and an input/output port. The body generates an ultrasound image based on a received signal from an ultrasound probe that transmits and receives an ultrasound wave. The input/output port is connected to the body. The body includes a body-side connection part having a plurality of terminal connection ports. The input/output port includes a port-side connection part that collectively holds terminals corresponding to the terminal connection ports. The body-side connection part and the port-side connection part are connected by a connection method chosen between an indirect connection method via a connector and a direct connection method not via the connector.

  • Publication number: 20180192998
    Abstract: A control device of an ultrasonic diagnostic apparatus includes a detector that detects a Doppler signal from a reception signal based on a reflected ultrasonic wave reflected on an internal portion of a subject, and a clutter component reducer that acquires a frequency spectrum based on the Doppler signal and reduces a clutter component from the acquired frequency spectrum based on symmetry of the clutter component which is distinguished from asymmetry of a blood flow component in the acquired frequency spectrum.

  • Publication number: 20140296710
    Abstract: An ultrasonic diagnostic apparatus is provided that improves ultrasonogram visibility without requiring an operator's effort in simultaneous display of multiple ultrasonograms. Ultrasonic diagnostic apparatus (100) includes: display range selection section (62) that sets a first display range on a first ultrasonogram and sets a second display range on a second ultrasonogram on the basis of the first display range set on the first ultrasonogram; and screen layout setting section (63) that sets a screen layout such that an ultrasonogram display area on a display screen is vertically or horizontally divided into a first display area and a second display area. Screen layout setting section (63) sets a screen layout such that the ultrasonogram display area is divided in a direction that allows the first ultrasonogram in the first display range to be displayed larger in the first display area.
