Abstract: The ultrasonic diagnostic apparatus according to the present embodiment includes an evaluating circuit, a frequency setting circuit, and a drive circuit. The evaluating circuit is configured to analyze a received signal of a predetermined depth based on received signals of ultrasonic wave to evaluate a degree of beam penetration to a deep portion. The frequency setting circuit is configured to set a transmission frequency based on a result evaluated by the evaluating circuit. The drive circuit is configured to generate a drive pulse based on the set transmission frequency.

Abstract: According to one embodiment, an ultrasound diagnosis apparatus includes processing circuitry. The processing circuitry acquires a change in a display parameter related to image display in a first bloodstream imaging mode of displaying a bloodstream signal acquired by an ultrasonic probe during execution of the first bloodstream imaging mode, and determines whether or not the display parameter after the change is more suitable for a second bloodstream imaging mode than for the first bloodstream imaging mode, an imaging method of the second bloodstream imaging mode differing from an imaging method of the first bloodstream imaging mode.

Abstract: According to one embodiment, a probe control apparatus includes processing circuitry. With respect to a scanning line in which a change has been made to a depth of field, the processing circuitry makes a change to a pulse repetition frequency in accordance with the depth of field after the change. The processing circuitry sets a new transmission voltage based on the pulse repetition frequency after the change.

Abstract: According to one embodiment, an ultrasonic diagnostic apparatus includes processing circuitry. The processing circuitry computes depths of field of each of scan lines based on an ultrasonic image. The processing circuitry computes a corrected transmission voltage that makes the depths of field of the scan lines substantially uniform. The processing circuitry executes control to transmit an ultrasonic beam based on the corrected transmission voltage.
