Abstract: An ultrasound diagnostic apparatus according to an embodiment includes a processing circuit. The processing circuit is configured to acquire first signal data of multiple frames through scan on a subject, extract second signal data of multiple frames by extracting a signal by nonlinear processing from the first signal data, identify an inappropriate signal point or an inappropriate frame from the second signal data, and generate third signal data based on an identification result of the inappropriate signal point or the inappropriate frame, and on the second signal data.

Abstract: An ultrasonic diagnostic apparatus of an embodiment includes an ultrasonic probe and processing circuitry. The ultrasonic probe transmits an ultrasonic wave to a subject, and receives the ultrasonic wave reflected by the subject. The processing circuitry acquires first ultrasonic data of the subject, based on the ultrasonic wave received by the ultrasonic probe. The processing circuitry extracts identification information that identifies a position of a local peak for each predetermined region of a frame represented by the first ultrasonic data. The processing circuitry outputs second ultrasonic data, based on the extracted identification information and ultrasonic data representing an object to be processed.

Abstract: An ultrasonic diagnosis apparatus according to an embodiment includes a processor. The processor acquires Doppler data that is obtained through ultrasonic transmission/reception in a Doppler mode and information about a type of the Doppler mode. The processor determines at least one executable measurement item for the Doppler data based on the information about the type of the Doppler mode.
