摘要: A method for manufacturing an acoustical stack use within ultrasound transducer comprises using a user defined center operating frequency of that is at least about 2.9 MHz. piezoelectric material and dematching are joined with assembly to form connection therebetween. The has first impedance *at one of* associated rugosity (Ra) waviness (Wa). second different than the Ra Wa. materials have ratio 2. thickness based on Ra, Wa,
