摘要:
Methods for fabricating high frequency ultrasound transducers are disclosed. The methods include fabricating an acoustic lens layer with a curved center section and two flat side sections. The curved section includes a center portion with a midpoint and an edge. The midpoint has a first thickness, and the edge has a second thickness. The center portion is fabricated so that an average of the first and second thicknesses is approximately equal to an odd multiple of a quarter-wavelength of the center frequency of the ultrasound transducer. The methods can also include bonding the lens layer to a matching layer that is operationally coupled to a transducer layer. The matching layer can include an epoxy layer and another layer. Bonding the lens layer includes bonding the other layer to the lens layer using the epoxy layer such that the other layer is positioned between the epoxy layer and the transducer layer.
