More Information
Summary:An ultrasound transducer array probe arranged as a layered structure having at least one layer of transducer array elements, and at least one further layer mounted in at least one of i) acoustic, and ii) thermal contact with said layer of transducer elements. The further layer has particles of a polymer core coated with at least one surface layer of a material that at least one of i) determines an acoustic impedance, and ii) a thermal conductivity of the further layer. The density of particles provides for a large number of particles to be in contact with neighboring particles, and the further layer is, at least across a part of its surface, coated with an electrically isolating layer that is so thin that the effect of the isolating layer on acoustic and thermal performance of the further layer is negligible.
