Abstract
A method for determining surface acoustic wave ray paths for an object. The method includes obtaining a representation of the object. A plurality of geodesics from a point on the object are determined and a plurality of surface acoustic wave ray paths are defined in response to the plurality of geodesics. The acoustic wave ray paths are used to determine a plurality of equally spaced surface acoustic wave fronts. In one application the surface acoustic wave fronts may then be used in a synthetic aperture focusing technique to obtain an image of the object.
