Abstract
An ultrasound diagnostic device includes a transmitter that causes an ultrasound probe including a plurality of transducers aligned in an azimuth direction to perform a plurality of set transmissions including a plurality of types of ultrasound transmissions for a transmission line which is common, while changing a position of the transmission line in the azimuth direction, a receiver that acquires, from the ultrasound probe, received signals based on reflected waves for the plurality of types of ultrasound transmissions and generates a plurality of types of acoustic line signals, and a hardware processor that generates an imaging signal based on the plurality of types of acoustic line signals. During a time interval between the plurality of types of the ultrasound transmissions in a first set transmission, the transmitter performs at least one of the plurality of types of ultrasound transmissions in a second set transmission.
