Beschreibung
Zusammenfassung:	A system for improving the acoustic performance of an ultrasound transducer by reducing artifacts within the acoustic spectrum is disclosed. The system includes an acoustic layer having an array of acoustic elements, a dematching layer coupled to the acoustic layer and having an acoustic impedance greater than an acoustic impedance of the acoustic layer, and an interposer layer coupled to the dematching layer and comprising a substrate and a plurality of conductive element. The interposer layer is formed to have an acoustic impedance lower than the acoustic impedance of the dematching layer. The ultrasound transducer also includes an integrated circuit coupled to the interposer layer and electrically connected to the array of acoustic elements through the dematching layer and the interposer layer.
