Abstract
The phased-array probe to be received on a probe receiving area of a wedge generally has a probe housing, a plurality of acoustic transducer elements disposed in the probe housing and distributed along a length of a working surface of the probe housing, and a matching layer covering the plurality of acoustic transducer elements and extending to cover an extended region of the working surface of the probe housing such that the matching layer forms a closed contact with an upper end of an acoustic damping junction of the wedge when the working surface of the probe housing of the phased-array probe is received on the probe receiving area of the wedge, wherein the closed contact prevents acoustic energy from being reflected from the extended region of the working surface of the probe housing.
