Title
(EN) ULTRASOUND TRANSDUCER ASSEMBLY
(ZH) 超声波换能器组件
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 transducerlayer. A plurality of kerfs extend 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.
