1. A method of constructing an ultrasound transducer, comprising:
fabricating an acoustic lens layer having a center curved section and two flat side sections, wherein fabricating the center curved section includes fabricating a center portion having a midpoint and two endpoints such that the center portion has a first thickness at the midpoint and a second thickness at each of the two endpoints, and wherein an average of the first thickness and the second thickness is substantially equal to an odd multiple of a ¼ wavelength of a center frequency of the ultrasound transducer; and
bonding the lens layer to a matching layer operationally coupled to a transducer layer, the matching layer comprising a first matching layer comprising an epoxy, and wherein bonding the lens layer comprises bonding a second matching layer to the lens layer using the first matching layer such that the second matching layer is positioned between the first matching layer and the transducer layer.
