Claim 6:
7. An ultrasound diagnostic device, comprising:
a transmitter connected to an ultrasound probe that includes a plurality of transducers aligned in an azimuth direction, the transmitter being configured to cause the plurality of transducers of the ultrasound probe to perform a plurality of set transmissions while changing a position of the transmission line in the azimuth direction of the ultrasound probe, wherein each set transmission of the plurality of set transmissions includes a pair of ultrasound transmissions of different polarity for a respective transmission line and wherein the pair of ultrasound transmissions for the each set transmission of the plurality of set transmissions are performed before a successive one of the plurality of set transmissions is performed;
a receiver configured to acquire, from the ultrasound probe, received signals based on reflected waves for the pair of ultrasound transmissions and generate a plurality of types of acoustic line signals including a first acoustic line signal and a second acoustic line signal; and
a hardware processor configured to detect a virtual image signal part of each of a plurality of types of acoustic line signals, perform treatment on the virtual image signal part of the acoustic line signal having the detected virtual image signal part by deleting the virtual image signal part or replacing the virtual image signal part by a corresponding signal part of a previous acoustic line signal line data of a same polarity, and generate an imaging signal based on the plurality of types of acoustic line signals including the treated acoustic line signal,
wherein a time interval between the pair of ultrasound transmissions in the each set transmission of the plurality of set transmissions differs from a time interval between two consecutive ultrasound transmissions each included in different set transmissions of the plurality of set transmissions, and
wherein the hardware processor is configured to perform cross-correlation processing of the first acoustic line signal and the second acoustic line signal and detects a signal part that is not present in another acoustic line signal as the virtual image signal part.
