  • Publication number: 20200015787
    Abstract: An ultrasound signal processing device performs transmission events by an ultrasound probe having transducer elements, generates a sub-frame acoustic line signal for each transmission event based on reflected ultrasound, and synthesizes sub-frame acoustic line signals to generate a frame acoustic line signal. A transmitter causes the ultrasound probe to transmit ultrasound beams to an ultrasound main irradiation area. A receiver generates receive signals for the transducer elements. A delay-and-sum calculator sets a target area in the ultrasound main irradiation area, and performs delay-and-sum calculation with respect to the receive signals from measurement points in the target area to generate a sub-frame acoustic line signal. The target area has, in a depth range shallower than a focal point, a width in the transducer element array direction that decreases as the depth decreases. A synthesizer synthesizes sub-frame acoustic line signals.

  • Patent number: 10080547
    Abstract: An ultrasound diagnostic device to which an ultrasound probe having a plurality of transducer elements is connectable. The ultrasound diagnostic device includes ultrasound signal processing circuitry operating as: a delay-and-sum processor; a determiner; and a velocity value calculator. The determiner determines whether adjustment of a velocity value for a partial area in a subject is necessary, based on acoustic line signal intensities for a specific measurement point in the partial area and other measurement points in the partial area. The specific measurement point is selected from among measurement points in the partial area based on acoustic line signals for the measurement points in the partial area. The velocity value calculator, when the determiner determines that velocity value adjustment is necessary, calculates an adjusted velocity value for the partial area by using the acoustic line signal for the specific measurement point.
