Claim 14:
15. A non-transitory computer readable storage medium storing therein a computer readable program causing a computer to perform ultrasound signal processing comprising:
causing an ultrasound probe including a plurality of transducers aligned in an azimuth direction to perform a plurality of set transmissions while changing a position of the transmission line in the azimuth direction, each set transmission of the plurality of set transmissions consisting of a first ultrasound transmission and a second ultrasound transmission with different drive pulse polarities for a respective transmission line;
acquiring, from the ultrasound probe, received signals based on reflected waves for the first ultrasound transmission and the second ultrasound transmission to generate a first acoustic line signal based on a reflected wave related to the first ultrasound transmission and generate a second acoustic line signal based on a reflected wave related to the second ultrasound transmission; and
generating an imaging signal based on the first acoustic line signal and the second acoustic line signal,
wherein in the transmitting, during a time interval between the first ultrasound transmission and the second ultrasound transmission in a first set transmission of the plurality of set transmissions, a first ultrasound transmission or a second ultrasound transmission in a second set transmission of the plurality of set transmissions that differs from the first set transmission of the plurality of set transmissions is performed and a further acoustic line signal is generated from the first ultrasound transmission or the second ultrasound transmission in the second set transmission,
wherein the first acoustic line signal, the second acoustic line signal, and the further acoustic line signal are stored in the first memory, the second memory, and the third memory in accordance with a transmission order,
wherein the computer causes a row of transmit transducers selected from among the plurality of transducers to transmit an ultrasound beam to perform the ultrasound transmission, and
wherein a transmission line related to the first set transmission and a transmission line related to the second set transmission are separated from each other by more than ½ of the length of the row of the transmit transducers in the azimuth direction.
