ABSTRACT:
An ultrasonic diagnosing apparatus transmits an ultrasonic wave into a subject under examination, thereby obtaining a tomogram and blood flow information of the subject. This ultrasonic diagnosing apparatus is equipped with an ultrasonic probe provided with a transducer array, in which a plurality of ultrasonic transducer elements are arranged, and a Doppler transducer independent of this transducer array, and switching devices for switching the operation mode of a transmitter/receiver system of the transducer array of this ultrasonic probe. The transducer array is used for transmission and reception of the ultrasonic wave when obtaining a tomogram and is used for either the transmission or reception of a continuous ultrasonic wave when obtaining blood flow information. The Doppler transducer is used for either the transmission or reception of the continuous ultrasonic wave only when obtaining the blood flow information.
