ABSTRACT:
An ultrasonic diagnostic apparatus comprises at least one piezoelectric transducer which is moved in a scanning process. A first transmission signal and a second transmission signal are different from each other. One of the first and second transmission signals is selectively applied to the transducer. The transducer converts the applied one of the first and second transmission signals into a beam of corresponding ultrasonic wave. The transducer emits the ultrasonic wave beam toward an examined body and receives an echo of the ultrasonic wave beam from the examined body. The transducer converts the received echo into a corresponding received signal. A first signal processor and a second signal processor have different characteristics. The received signal is selectively applied to one of the first and second signal processors to be processed thereby. A sectional image of the examined body is generated on the basis of an output signal from one of the first and second signal processors.
