Patent ID: 8360980

Claim:
An ultrasonic diagnosis apparatus which acquires an ultrasonic image by scanning a scan plane in a subject administered with bubbles of a contrast medium by an ultrasonic wave, said ultrasonic diagnosis apparatus comprising: an ultrasonic probe configured to transmit the ultrasonic wave to the subject and to receive an echo signal from the subject; a drive signal generating unit configured to generate a drive signal for driving the ultrasonic probe; and a control unit configured to control the drive signal generating unit to temporally and continuously repeat, for a predetermined period of time, first transmissions to the scan plane to destroy a part of the bubbles of the contrast medium at part of a desired blood vessel and to restrain the contrast medium from flowing into the desired blood vessel in the scan plane, the first transmissions including transmissions of a first ultrasonic wave and transmissions of a second ultrasonic wave, the first ultrasonic wave being transmitted to at least one first predetermined area in the scan plane and having a sound pressure to a degree of not substantially destroying the bubbles of the contrast medium for acquiring a circulation image of a blood stream with regard to the at least one first predetermined area, the second ultrasonic wave being transmitted to a second predetermined area, which does not overlap the at least one first predetermined area in the scan plane, and having a sound pressure to a degree of destroying a part of the bubbles of the contrast medium at part of the desired blood vessel and restraining the contrast medium from flowing into the desired blood vessel during the predetermined period of time.
