A transducer assembly operable to transmit ultrasonic energy in a desired direction towards a zone adapted to be acoustically coupled to an object or area of interest is disclosed which has a transducer layer, a backing material disposed behind the transducer layer with respect to the desired direction, and a back-matching layer disposed between the transducer layer and the backing material to reflect towards the transducer layer part of the ultrasonic energy directed from the transducer layer to the backing material. The backing layer has an acoustic impedance higher than the acoustic impedance of the back-matching layer. The back-matching material has an impedance less than the impedance of the transducer layer and the transducer layer has a thickness greater than a &#xbc; of the wavelength of the ultrasound waves the assembly is configured to generate. A process for manufacturing a transducer assembly is also disclosed.
