Abstract
A method for detecting and characterizing flaws in an object having an arbitrary-shaped geometry. The present invention uses a synthetic aperture focusing technique (SAFT) which enables maximum aperture imaging. Maximum aperture imaging is attained by determining whether a plurality of reconstruction points within an object are in the width of a transmitted ultrasonic sound wave.
