Abstract:
1. An ultrasonic diagnostic apparatus comprising: an ultrasonic probe which transmits ultrasonic waves to a subject injected with contrast medium bubbles, receives reflected ultrasonic waves from the subject, and generates echo signals on the basis of the received ultrasonic waves; a transmission unit configured to perform, via the ultrasonic probe, a series of first transmissions for a plurality of frames at a first acoustic pressure, which is an acoustic pressure not to destroy substantially the contrast medium bubbles but to obtain an image of a blood flow circulation, and to perform a series of second transmissions for a plurality of frames at a second acoustic pressure to destroy the contrast medium bubbles; a control unit configured to control the transmission unit in such a manner that the series of first transmissions and the series of the second transmissions are performed alternatively; and an image generating unit configured to generate a first image by performing a luminance value holding computation using echo signals of at least two frames obtained in the first transmissions.
