Beschreibung
Zusammenfassung:	An ultrasound apparatus includes an ultrasound transducer array configured to transmit and receive ultrasound signals and an acoustic lens that includes signal-attenuating particles in a polymer matrix configured to provide signal attenuation and impedance matching for the ultrasound signals. The acoustic lens is disposed over a first surface of the ultrasound transducer array. The signal-attenuating particles include PEBAX.
