ABSTRACT:
The present invention relates to a device for moving a transducer of an ultrasonic probe in an ultrasonic diagnostic apparatus for acquiring a 3-dimensional ultrasound image. A motor for generating power to move the transducer and guide rails for guiding the movement of the transducer are mounted to the frame. The rotational force of a driving shaft of the motor is transmitted to a driven shaft through pulleys and belts. A portion of a wire is wound around the driven shaft and both ends of the wire are fixed to two opposing surfaces of the transducer. A reel having a spiral groove on the peripheral surface is coupled to the driven shaft. The wire is wound along the spiral groove.
