Abstract:
1. A matching layer for an ultrasound probe comprising a plurality of sublayers attached together, the sublayers having different impedance values, a first sublayer of the plurality of sublayers being disposed adjacent to an element of a transducer of the ultrasound probe, a last sublayer of the plurality of sublayers being disposed adjacent to a target, the impedance value of the first sublayer being less than or equal to the impedance value of the element of the transducer, the impedance value of the last sublayer being greater than or equal to the impedance value of the target, the impedance values of the sublayers decreasing from the first to the last sublayer, wherein each of said sublayers comprises a plurality of materials having different impedance values, and one of said materials is distributed in another of said materials.
