Ultrasound diagnostic device and non-transitory computer readable storage medium

An ultrasound diagnostic device, comprising:

• a transmitter that causes an ultrasound probe including a plurality of transducers aligned in an azimuth direction to perform a plurality of set transmissions each 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,
• wherein a time interval between the plurality of types of ultrasound transmissions in the set transmission is greater than a time interval between two consecutive ultrasound transmissions each included in a different set transmission.
