BONE SURFACE IMAGE RECONSTRUCTION USING ULTRASOUND

摘要

An ultrasonic transducer element can configured to generate ultrasonic energy directed into tissue of a subject and configured to receive a portion of the ultrasonic energy reflected by a target located within the tissue. The ultrasonic transducer can include a surface configured to provide or receive the ultrasonic energy, the surface including an area of greater than or equal to about 4lambda2, or the ultrasonic transducer element can be included in an array having a spacing between at least two adjacent ultrasound elements of less than or equal to about ½lambda, and the array comprising an aperture that is at least approximately symmetrical in two axes. A three-dimensional representation of one or more of a location, shape, or orientation of at least a portion of the target can be presented via the display.
