Abstract
An ultrasound transducer having an acoustic backing layer made of an aerogel material is disclosed. The ultrasound transducer comprises an acoustic element for transmitting and receiving ultrasound waves. An aerogel acoustic backing layer is bonded to the back side of the acoustic element. A matching layer may be attached to the front side of the acoustic element. The ultrasound transducer may be electrically connected using electrodes directly connected to the acoustic element. Alternatively, the aerogel acoustic backing may be coated with a metalized layer or doped so that it is electrically conductive. Then, the electrodes may be connected directly to the aerogel acoustic backing.
