Abstract
Various methods and systems are provided for an ultrasound transducer structure for an ultrasound probe and methods of manufacturing thereof. In one example, the ultrasound transducer structure may include a lens, an acoustic stack disposed on the lens, and an acoustic backing material bonded to a side of the acoustic stack facing away from the lens without any intervening layer between the acoustic backing material and the acoustic stack, such that the acoustic backing material is in face-sharing contact with the side of the acoustic stack, wherein the acoustic backing material is composed of a solidified blend comprising a backing polymer.
