Abstract
An ultrasound diagnostic apparatusincludes a transducer array, a transmission unitthat transmits an ultrasonic pulse FP and an ultrasonic pulse SP having phases inverted from each other on the scanning line from the transducer arraymultiple times, a reception unitthat acquires reception signals from an output signal of the transducer array, a quadrature detection unitthat performs quadrature detection on the reception signals to acquire IQ signal strings, a tissue velocity detection unitthat detects a velocity of a tissue in a subject based on the IQ signal strings, a phase correction unitthat corrects phases of the IQ signal strings, a pulse inversion addition unitthat adds IQ signals corresponding to the ultrasonic pulse FP and IQ signals corresponding to the ultrasonic pulse SP using the corrected IQ signal strings to acquire added signals, and an image generation unitthat generates an ultrasound image from the added signals.
