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.

L'ensemble transducteur à ultrasons comporte un circuit souple auquel un réseau de transducteurs à ultrasons et des circuits intégrés sont raccordés en cours de fabrication de l'ensemble transducteur à ultrasons. Les circuits intégrés et les éléments transducteurs sont raccordés au circuit souple, qui est essentiellement plat. Les contacts des éléments transducteurs se trouvent essentiellement sur le même plan de sorte que le contact électrique avec les lignes de signal et de masse du circuit souple est établi sans ponts conducteurs vers des électrodes éloignées. Dans une version de l'invention où les éléments transducteurs sont disposés en un réseau cylindrique, les espaces sont entièrement comblés par un matériau de renfort ayant une impédance acoustique assez faible. L'intégrité structurale est améliorée et la mise à la masse est facilitée au moyen de disques conducteurs raccordés aux extrémités de l'ensemble transducteur.
