Title
(EN) ULTRASOUND TRANSDUCER ASSEMBLY
(FR) ENSEMBLE TRANSDUCTEUR ULTRASONORE
Abstract
(EN)
Ultrasound transducer assemblies and associated systems and method are disclosed herein. In one embodiment, an ultrasound transducer assembly includes at least one matching layer overlies a transducer layer. A plurality of kerfs extends at least into the matching layer. In some aspects, the kerfs are at least partially filled with a filler material that includes microballoons and/or microspheres.
(FR)
L’invention concerne des ensembles transducteurs ultrasonores et des systèmes et un procédé associés. Dans un mode de réalisation, un ensemble transducteur ultrasonore comprend au moins une couche d’adaptation recouvrant une couche de transducteur. Une pluralité de saignées s'étend au moins dans la couche d'adaptation. Selon certains aspects, les saignées sont au moins partiellement remplies d'une matière de remplissage qui comprend des microballons et/ou des microsphères.
