Abstract:
An ultrasonic diagnostic apparatus comprising:a transmission/reception device which transmits for a plurality of times ultrasonic waves having an intensity capable of destructing a contrast agent to one scanning plane of an object to which the contrast agent has been injected and receives a reflected wave group from the object; a data generator which generates a plurality of accumulative addition data having different time phases based on at least one of a plurality of reflected waves constituting a plurality of continuous frames in the reflected wave group and generates subtraction data from a reflected wave received from the object with a predetermined timing; and an image information generator which generates calculated data having an operation value to which a plurality of the accumulative addition data has been accumulatively added and from which the subtraction data has been subtracted, and generates ultrasonic wave image information concerning the scanning plane based on the calculated data.
