力する出力制御手段と、 を備えた超音波診断装置。[Claims for Utility Model Registration] An ultrasound system that transmits an ultrasound beam toward a subject, receives reflected echoes from the subject, and obtains Doppler signals from the reflected echoes to obtain blood flow information. In a sonographic diagnostic device, the gain is adjusted to obtain echoes due to the blood flow of the subject, and a first receiving system receives reflected echoes from the subject to obtain blood flow velocity, and a first receiving system obtains echoes due to clutter of the subject. The output of the first receiving system is compared with the output of the second receiving system, and the gain of the second receiving system is adjusted to obtain the velocity of the clutter by receiving the reflected echo from the subject. An ultrasonic diagnostic apparatus comprising: output control means for outputting the output of the first receiving system to the display means only when the output exceeds the output of the second receiving system.
