摘要： An array ultrasonic transducer precursor includes a body of piezoelectric material with a dielectric substrate bonded to a surface of the body. Circuit elements supported on the dielectric substrate include, in an active region, physically parallel signal conductors arranged in a pattern with spaces between adjacent ones of the conductors. Dicing saw cuts made in these spaces define individual circuit elements within the piezoelectric body. The circuit elements outside the active region include a set of resistive alignment elements in predetermined positions with reference to the pattern of signal conductors. The transducer precursor is mounted in a dicing saw fixture, and initial cuts made with the dicing saw remove portions of the resistive alignment elements. Locations of the initial cuts with reference to the resistive alignment elements are determined by measuring resistances of the resistive alignment elements after the initial cuts.

摘要： In an ultrasound imaging system, a multiplexer connects a beamformer to a multi-row transducer array, where the array has more electrically independent transducer elements than the beamformer has channels, so as to provide dynamic selection and beamforming control of multi-row apertures. The multiplexer allows the active aperture to be scanned along at least one axis of the array and allows the shape of the active aperture to be varied electronically. The multiplexer, which supports transmit and receive apertures appropriate for synthetic aperture beamforming, is of modular construction, enabling multiplexers appropriate for transducer arrays with various numbers of rows and columns of elements to be easily assembled from a standard set of parts. The multiplexer is physically designed as a passive backplane into which various switch cards can be plugged. The card connectors are arranged in two parallel columns. Traces from system channels are distributed on the backplane; coaxial leads from transducer elements are connected to the switch cards.

摘要： A multi-row ultrasound transducer array having a central row of transducer elements and a pair of outermost rows of transducer elements on opposing sides of the central row. The corresponding elements of the outermost rows are connected in parallel to a respective signal lead. The area of each element in the central row is less than the combined area of each pair of elements of the outermost rows. The greater total area of the combined elements of the outermost rows as compared to the area of each element of the central row provides improved elevation performance (thinner and more uniform image slice, greater contrast resolution), especially in the very near field, as compared to conventional transducers. The array may further include one or more pairs of rows of elements intermediate the central row and the respective outermost rows. The corresponding elements of the intermediate rows are connected in parallel to respective signal leads. The combined area of each pair of elements of the intermediate rows is less than the combined area of each pair of elements of the outermost rows, but greater than the area of a central row element.

摘要： A method for fabricating "1.5D" and "2D" multilayer ultrasonic transducer arrays employs dicing saw kerfs, which provide acoustic isolation between rows. The kerfs are metallized to provide electrical connection between surface electrode layers and buried internal electrode layers. A multilayer piezoceramic transducer element for a "1.5D" or "2D" array produced by this method has higher capacitance, and accordingly provides better transducer sensitivity, in comparison to a single layer element.
