ABSTRACT:
A probe which is inserted into a lumen to obtain an ultrasonic tomogram using mechanical scanning is disclosed. A cylindrical acoustic case is filled with a liquid medium which transmits sound waves, and an elliptical ultrasonic transducer is immersed therein in such a manner that it can be rotated by a motor. The diameter of the transducer parallel to its axis of rotation is greater than that perpendicular to the axis of rotation, so that the lateral resolution parallel to the axis of rotation is improved, as well as the sensitivity.
