ABSTRACT:
An ultrasonic imaging apparatus comprises an ultrasonic transducer having two ultrasonic transducer elements which rotatably arranged back to back at the distal portion of an endoscope and a motor provided in the operation section of the endoscope and coupled to the transducer through a drive shaft to rotate the transducer. A transducer drover alternately drives the transducer elements during one rotation of the transducer. A switching circuit alternately switches the echo signals from the transducer elements during one rotation of the transducer. The echo signals of the transducer elements through the switch circuit are signal-processed and supplied to a TV monitor to display a tomographic image.
