摘要：
An acoustical stack for an ultrasound probe comprises a piezoelectric layer having top and bottom sides and a plurality of matching layer sections forming a matching layer structure. Each of the matching layer sections comprises a spring layer comprising a first material and a mass layer comprising a second material that is different than the first material. The spring layer within the matching layer section that is positioned closest to the piezoelectric layer is thinner than the spring layer within the other matching layer sections.
