    摘要： The present invention relates to a device for guiding the movement of a transducer of an ultrasonic probe in an ultrasonic diagnostic apparatus for acquiring a 3-dimensional ultrasound image. A pair of guide rails (22) is disposed near both side-ends of the transducer and is disposed apart therefrom by predetermined gaps. Slots (24) are formed lengthwise at side surfaces of the guide rails. Each slot has a bottom wall and a side wall. Bearings coupled to the both side-ends of the transducer are received in the slots and roll on the bottom walls of the slots. First magnets (42) are fixed to the both side-ends of the transducer and second magnets (44) are fixed to the side walls of the slots along the overall length of the slots. The first magnets are received in the slots and are disposed opposite to the second magnets so that repulsive forces are generated therebetween.

    摘要： An ultrasonic probe for three dimensional scanning includes a one­dimensional array transducer which is mechanically swept back and forth. As the array transducer is swept in one direction the array scans the volumetric region with image planes which are scanned from left to right. As the array transducer is swept in the opposite direction the direction of beam scanning is reverse so that the volumetric region is scanned with image planes which are scanned from right to left. The reversal of the beam scanning direction causes the scanned planes to be substantially aligned, resulting in a reduction in scanning artifacts.

    摘要： An ultrasonic imaging catheter apparatus and a method of using the same to scan the inner wall of a body lumen. The ultrasonic imaging catheter apparatus comprises: (a) a flexible elongate element adapted for insertion into a body lumen, the elongate element having distal and proximal ends; (b) an ultrasonic transducer generating and detecting ultrasonic energy disposed proximate the distal end of the elongate element; (c) a reflective member disposed proximate the ultrasonic transducer and optionally rotatable with respect to an axis of the body lumen, wherein the reflective member is adapted to reflect (i) ultrasonic energy generated by the ultrasonic transducer to a wall of the body lumen and (ii) ultrasonic energy reflected by the wall back to the transducer; and (d) an actuator (140), for example, an electroactive polymer actuator, adapted to change the angle of incidence of the ultrasonic energy relative to the reflective member.
