Abstract:
1. An ultrasonic diagnostic apparatus, comprising: an ultrasonic probe; a transmitter/receiver configured to transmit, after a contrast medium is injected to an object, by the ultrasonic probe, a first ultrasonic pulse and a second ultrasonic pulse that have different center frequency from each other, and a third ultrasonic pulse that has corresponding frequency component characteristics resulting from a combined pulse obtained by combining the first and second ultrasonic pulses, wherein the first, second, and third ultrasonic pulses are transmitted to the object one after another, and to receive, by the ultrasonic probe, each of reception echoes corresponding to the ultrasonic pulses; a signal processor configured to process the reception echoes corresponding to the first, second, and third ultrasonic pulses, and to generate a processed signal; and an image generating processor configured to generate a contrast image by use of the processed signal.
