Abstract
A transmitting/receiving unit transmits an ultrasound wave to an object at a first rate in accordance with a first code, transmit an ultrasound wave to the object at a second rate in accordance with a second code complementary to the first code, and receives the first and second reception signals. The first and second reception signals are convoluted in the second and first codes respectively. The phase difference between the two signals represents the motion of the tissue of the object between the first and second rates. The first or second reception signal is compensated on the basis of the phase difference. The compensated first and second reception signals are convoluted in the first and second codes respectively. The two signals are added to generate a third reception signal. Image data is generated on the basis of the third reception signal.
