Abstract: An ultrasound diagnostic apparatus includes a drive circuit configured to transmit a drive signal to an ultrasound transducer, a receiving circuit configured to receive an echo signal from the ultrasound transducer, and a processor. The processor obtains, based on the echo signal or a user input, target information containing at least one of a distance from the ultrasound transducer to a target region containing liquid or a size of the target region, and sets, based on the target information, a drive condition under which an acoustic streaming generating ultrasound transmitted by the ultrasound transducer generates acoustic streaming in the liquid in the target region.

Abstract: An ultrasound imaging apparatus includes: a processor configured to transmit a signal for transmitting an ultrasound wave toward an observation point from an ultrasound probe, receive an echo signal that is obtained by converting an ultrasound wave into an electrical signal, generate information relating to an attenuation factor by comparing a first intensity of a first echo signal with a second intensity of a second echo signal, the first echo signal being a signal which, after being transmitted via a first path and being reflected by the observation point, has been received via the first path, the second echo signal being a signal which, after being reflected by the observation point, has been received via a second path, the second path being a path that is different from the first path and that is equal in length to the first path, and generate evaluation information representing a comparison result.
