Claims

[Scope of utility model registration request]

An ultrasonic pulse probe for B-mode tomographic images and a Doppler probe are integrated, and a wave transmitting and receiving transducer provided in the ultrasonic pulse probe and a wave transmitting and receiving transducer provided in the Doppler probe are integrated. are fixed at predetermined relative positions, and placed at a position where the B-mode scanning plane and the Doppler beam approach and intersect at a desired diagnosis site depth. An ultrasound probe that is excited by a continuous wave and has both excitation frequencies set to different frequencies, and is characterized in that the Doppler beam and the flow velocity direction of the diagnostic site to be measured can be set at a desired angle depending on the clarity of the B-mode tomographic image. .
