ABSTRACT:
An ultrasonic diagnostic apparatus comprises a probe having at least one electro-acoustic transducing element, a motor for imparting a sector motion to the probe, a pulse oscillator for energizing the electro-acoustic transducing element to generate ultrasonic pulses, and a signal processing circuit connected to receive from the electro-acoustic transducing element electric signals corresponding to the ultrasonic signals received by the probe and to process the electric signals so as to provide information on the living body being examined. The apparatus further comprises a first control circuit connected to receive first reference signals of a predetermined frequency and control the rotation of the motor according to the first reference signals, a second control circuit connected to receive second reference signals and control the rotation of the motor according to the second reference signals, and a switching circuit for connecting the first and second control circuits alternatively to the motor.
