Abstract
An ultrasonic diagnosis apparatus comprises an ultrasonic probe like a biplane probe having two ultrasonic transducers, a switch for selecting one of the ultrasonic transducers, a transmitting-receiving system for driving an ultrasonic transducer selected by the switch to transmit and receive ultrasonic waves, a B-mode image producing means responsive to a receive signal from the ultrasonic transducer driven by the transmitting-receiving system for producing an ultrasonic cross-sectional image, a scanning-plane mark generator for generating a scanning-plane mark indicating the positional relationship between the ultrasonic scanning plane formed by the ultrasonic transducer selected by the switch and the other ultrasonic scanning plane formed by the other ultrasonic transducer and a TV monitor for displaying a superimposition image in which the scanning-plane mark generated by the scanning-plane mark generator is superimposed on the ultrasonic cross-sectional image produced by the B-mode image producing system.
