Abstract
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.

-13. (canceled)
A method of constructing an ultrasound transducer assembly, the method comprising:
- bonding an upper surface of a piezoelectric layer to a lower surface of a matching layer;
- bonding a lower surface of the piezoelectric layer to a dematching layer;
- forming a first plurality of kerfs extending into the matching layer;
- and
- forming a second plurality of kerfs extending through the matching layer, the piezoelectric layer and the dematching layer, wherein a depth of the first plurality of kerfs is less than a depth of the second plurality of kerfs.
2 more elements
An ultrasound transducer assembly, comprising:
- a piezoelectric layer comprising a plurality of piezoelectric transducer elements configured emit ultrasound energy;
- a plurality of matching layers overlaying the piezoelectric layer, wherein a Z-axis extends through the plurality of matching layers and the piezoelectric layer;
- and
- a plurality of first kerfs and a plurality of second kerfs extending into at least the plurality of matching layers, wherein the first kerfs have a first depth with respect to the Z-axis, wherein the second kerfs have a second depth with respect to the Z-axis, wherein the second depth is greater than the first depth, and wherein the kerfs are at least partially filled with a composite filler material comprising two or more materials.
