ABSTRACT:
For use in ultrasound pulse-echo imaging and neurosurgery systems, a plano-concave lens of elliptical shape is positioned in front of a transducer for producing an extremely narrow ultrasonic beam, and at the same time provides a large aperture to maximize the ultrasound power output from the transducer and the capture angle of reflected echoes. The lens is preferably formed of plastic, selected from a wide variety of available plastics in accordance with desired acoustical properties for a given application, and is preferably bonded to a flat, disc-shaped transducer. By proper selection of the material used to construct the lens it is possible to produce the correct amount of transducer apodization.
