Abstract
An ultrasound transducer and an ultrasound imaging system including an acoustic layer with a plurality of transducer elements and a dematching layer coupled to the acoustic layer. The dematching layer has an acoustic impedance greater than the acoustic layer and the dematching layer has a thickness that varies in order to alter a bandwidth of the ultrasound probe.
