Abstract:
An ultrasonic diagnostic apparatus comprising:a transmitting/receiving unit configured to transmit an ultrasound wave to an object to be examined at a first rate in accordance with a first code, receive a first reception signal from the object, transmit an ultrasound wave to the object at a second rate in accordance with a second code complementary to the first code, and receive a second reception signal from the object; a first processor configured to convolute the second code in the first reception signal, convolute the first code in the second reception signal, and detect a phase difference between the two signals, the phase difference representing a motion of a tissue of the object between the first and second rates; a second processor configured to compensate at least one of the first and second reception signals on the basis of the phase difference; a third processor configured to convolute the first and second codes in the compensated first and second reception signals, respectively, add the two signals, and generate a third reception signal; and a unit configured to generate image data on the basis of the third reception signal.
