摘要： An ultrasound transducer assembly of the present invention includes a flexible circuit to which an ultrasound transducer array and integrated circuitry are attached during fabrication of the ultrasound transducer assembly. Integrated circuitry and transducer elements are attached to the flexible circuit while the flexible circuit is in a substantially flat shape. The contacts of the transducer elements are positioned on substantially the same plane such that electrical contact with signal and ground lines on the flexible circuit is established without the need for conductive bridges to physically remote electrodes. In an embodiment of the invention wherein the transducer elements are arranged in a cylindrical array, gaps are entirely filled with backing material having a relatively low acoustic impedance. Structure integrity is enhanced and a path to ground facilitated by electrically conductive disks attached to the ends of the transducer assembly.

摘要： In a mechanical sector scanner, a first bevel gear is mounted on the end of an output shaft of a motor, and an ultrasonic transducer is rotatably supported for rotating about a scanning axis transverse to the output shaft. A second bevel gear engaging the first bevel gear is mounted on the back surface of the transducer. The output shaft oscillates about an output axis. Oscillations of the output shaft are coupled to the transducer by the bevel gears. The second gear has a plurality of teeth arranged in an arc less than completely around the scanning axis, and the second gear is so disposed that the back surface of the transducer is nearer to the scanning axis than the teeth.

摘要： An ultrasonic transducer array having a plurality of transducer elements aligned along an array axis in an imaging plane. Each transducer element includes a piezoelectric substrate and further includes a rear electrode applied to the substrate's rear surface and a patterned front electrode applied to the substrate's front surface. A conductive or metalized acoustic matching layer overlays the patterned front electrode. The front electrode is specially patterned along an elevation axis perpendicular to the imaging plane, so as to apodize the emitted ultrasonic beam in the elevation plane. The pattern follows a predetermined tapered weighting function, preferably one that approximates a Hamming weighting function. Slots, oriented parallel with the array axis, are cut into the piezoelectric substrate's front surface, to form a plurality of subelements. This further isolates these portions of the piezoelectric substrate not overlaid by the patterned front electrode, thereby enhancing beam apodization.
