  • Ultrasound transducer element and method for providing an ultrasound transducer element
    Patent number: 8450910
    Abstract: An ultrasound transducer element includes a piezoelectric layer, a front end body, and a backing layer assembly. The piezoelectric layer extends between opposite front and back sides and is configured to transmit acoustic waves from the front side. The front end is body disposed proximate to the front side of the piezoelectric layer and is configured to emit the acoustic waves out of a housing. The backing layer assembly is disposed proximate to the back side of the piezoelectric layer. The backing layer assembly includes a first thermally conductive mesh disposed in a matrix enclosure. The first thermally conductive mesh is positioned to conduct thermal energy away from the piezoelectric layer. In one aspect, the first thermally conductive mesh is a grid of elongated strands of a metal or metal alloy material oriented in at least one of transverse or oblique directions.

  • APPARATUS AND METHOD FOR INDICATING ULTRASOUND PROBE ORIENTATION AND ACTIVATION STATUS
    Publication number: 20100305448
    Abstract: An ultrasound probe has a probe casing and a light emitting diode (LED). The probe casing has an inner surface and an outer surface. The LED is mounted and contained entirely within the probe casing and the LED is configured to be illuminated when the probe is active.
