Abstract:
1. An ultrasound transducer element configured to be disposed in a housing, the transducer element comprising: a piezoelectric layer extending between opposite front and back sides, the piezoelectric layer configured to transmit acoustic waves from the front side; a front end body disposed proximate to the front side of the piezoelectric layer, the front end body configured to emit the acoustic waves out of the housing; and a backing layer assembly disposed proximate to the back side of the piezoelectric layer, the backing layer assembly including a first thermally conductive mesh disposed in a matrix enclosure, wherein the first thermally conductive mesh is positioned to conduct thermal energy away from the piezoelectric layer, and wherein the front side of the piezoelectric layer defines an acoustically transmitting footprint from which the acoustic waves can be transmitted by the piezoelectric layer, the first thermally conductive mesh laterally extending beyond the footprint in at least one direction.
