Abstract
A hand-held portable ultrasonic scanning probe for use with energizing and receiving means for imaging sections of a body includes a fluid-filled enclosure coupled to a handle portion which houses a DC drive motor. The output shaft of the drive motor is directly coupled to a level wind drive screw. A holder assembly incorporating a pawl which coacts with the drive screw and a plano-concave transducer moves back and forth across the drive screw as a result of the DC motor output shaft rotation. The linear travel of the transducer creates a linear scan thereby eliminating the diagnostic imaging problems of sector scans.
