ABSTRACT:
A transducer drive assembly is disclosed having particular application for use in medical diagnostic imaging systems. The drive assembly includes a rotor coupled to drive means for rotation about its longitudinal axis. The rotor is formed such that it includes an integrally formed contact plate which extends upwardly from a generally flat rotor face at a given angle. A transducer is carried in a cradle which is mounted for pivotal movement, and includes a lower base portion having a generally cylindrical cross section. The lower base portion of the cradle is disposed such that it is maintained in physical contact with the rotor contact plate at all times. The rotation of the rotor applies force to the lower base of the cradle resulting in the oscillation of the cradle about the pivot points. The transducer is thereby oscillated back and forth about the pivot points in a uniform and continuous movement so long as the rotor continues to rotate.
