Abstract:

This document is a state-of-the-art survey of advanced acoustic imaging techniques developed for nondestructive testing and medical applications. Several techniques are evaluated simple mechanical scanning systems, array imaging, acoustic holography, synthetic aperture, Bragg imaging, and ray tracing. Examples of practical imaging systems that employ these techniques are described and compared, and in order to put these systems into proper chronological perspective, an appendix is included that briefly discusses older acoustic imaging techniques.
