ABSTRACT:
A linear array ultrasonic transducer is provided primarily for use in a medical diagnostic examination device in which an ultrasonic beam is projected toward an object to be examined, thereby to examine the condition of the tissues of that object. The linear array ultrasonic transducer comprises an array of tiny oscillatory elements and electrode leads connected by a conductive adhesive to facilitate the fabrication, and two registering layers and a lens layer mounted on the front sides of the tiny oscillatory elements so that an image of high resolution may be produced.
