ABSTRACT:
A compound lens for focusing ultrasound emitted from an ultrasound probe having an array of piezoelectric transducer elements. The compound lens has an inner lens part with a convex cylindrical front face and a rear face which is acoustically coupled to the front face of the transducer array, and an outer lens part with a concave cylindrical rear face which is acoustically coupled to the convex cylindrical front face of the inner lens part. The inner lens part may be in the form of a conventional silicone rubber focusing lens. The outer lens part is made of an acoustic medium having a higher acoustic velocity and greater durability than silicone rubber, e.g., polymethylpentene, nylon and high-density polyethylene. Also the outer lens part has greater chemical resistance than silicone rubber.
